+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read

+INSTALLING GLPK ON YOUR COMPUTER
+********************************
+
+Unpacking the distribution file
+-------------------------------
+The GLPK package (like all other GNU software) is distributed in the
+form of a packed archive. It is one file named `glpk-X.Y.tar.gz', where
+`X' is the major version number and `Y' is the minor version number;
+for example, the archive name might be `glpk-4.15.tar.gz'.
+
+In order to prepare the distribution for installation you should:
+
+1. Copy the GLPK distribution file to a working directory.
+
+2. Unpack the distribution file with the following command:
+
+      gzip -d glpk-X.Y.tar.gz
+
+   After unpacking the distribution file is automatically renamed to
+   `glpk-X.Y.tar'.
+
+3. Unarchive the distribution file with the following command:
+
+      tar -x < glpk-X.Y.tar
+
+   It automatically creates the subdirectory `glpk-X.Y' containing the
+   GLPK distribution.
+
+Configuring the package
+-----------------------
+After unpacking and unarchiving the GLPK distribution you should
+configure the package, i.e. automatically tune it for your platform.
+
+Normally, you should just `cd' to the directory `glpk-X.Y' and run the
+`configure' script, e.g.
+
+      ./configure
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It also creates file `config.h' containing platform-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+Running `configure' takes about a few seconds. While it is running, it
+displays some messages that tell you what it is doing. If you don't want
+to see the messages, run `configure' with its standard output redirected
+to `dev/null'; for example, `./configure > /dev/null'.
+
+By default both static and shared versions of the GLPK library will be
+compiled. Compilation of the shared librariy can be turned off by
+specifying the `--disable-shared' option to `configure', e.g.
+
+      ./configure --disable-shared
+
+If you encounter problems building the library try using the above
+option, because some platforms do not support shared libraries.
+
+The GLPK package has some optional features listed below. By default
+all these features are disabled. To enable a feature the corresponding
+option should be passed to the configure script.
+
+--with-gmp           Enable using the GNU MP bignum library
+
+   This feature allows the exact simplex solver to use the GNU MP
+   bignum library. If it is disabled, the exact simplex solver uses the
+   GLPK bignum module, which provides the same functionality as GNU MP,
+   however, it is much less efficient.
+
+   For details about the GNU MP bignum library see its web page at
+   <http://gmplib.org/>.
+
+--with-zlib          Enable using the zlib data compression library
+
+   This feature allows GLPK API routines and the stand-alone solver to
+   read and write compressed data files performing compression and
+   decompression "on the fly" (compressed data files are recognized by
+   suffix `.gz' in the file name). It may be useful in case of large
+   MPS files to save the disk space.
+
+   For details about the zlib compression library see its web page at
+   <http://www.zlib.net/>.
+
+--enable-dl          The same as --enable-dl=ltdl
+--enable-dl=ltdl     Enable shared library support (GNU)
+--enable-dl=dlfcn    Enable shared library support (POSIX)
+
+   Currently this feature is only needed to provide dynamic linking to
+   ODBC and MySQL shared libraries (see below).
+
+   For details about the GNU shared library support see the manual at
+   <http://www.gnu.org/software/libtool/manual/>.
+
+--enable-odbc        Enable using ODBC table driver (libiodbc)
+--enable-odbc=unix   Enable using ODBC table driver (libodbc)
+
+   This feature allows transmitting data between MathProg model objects
+   and relational databases accessed through ODBC.
+
+   For more details about this feature see the supplement "Using Data
+   Tables in the GNU MathProg Modeling Language" (doc/tables.*).
+
+--enable-mysql       Enable using MySQL table driver (libmysql)
+
+   This feature allows transmitting data between MathProg model objects
+   and MySQL relational databases.
+
+   For more details about this feature see the supplement "Using Data
+   Tables in the GNU MathProg Modeling Language" (doc/tables.*).
+
+Compiling the package
+---------------------
+Normally, you can compile (build) the package by typing the command:
+
+      make
+
+It reads `Makefile' generated by `configure' and performs all necessary
+jobs.
+
+If you want, you can override the `make' variables CFLAGS and LDFLAGS
+like this:
+
+      make CFLAGS=-O2 LDFLAGS=-s
+
+To compile the package in a different directory from the one containing
+the source code, you must use a version of `make' that supports `VPATH'
+variable, such as GNU `make'. `cd' to the directory where you want the
+object files and executables to go and run the `configure' script.
+`configure' automatically checks for the source code in the directory
+that `configure' is in and in `..'. If for some reason `configure' is
+not in the source code directory that you are configuring, then it will
+report that it can't find the source code. In that case, run `configure'
+with the option `--srcdir=DIR', where DIR is the directory that contains
+the source code.
+
+Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+
+      CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+
+      env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Here are the `make' variables that you might want to override with
+environment variables when running `configure'.
+
+For these variables, any value given in the environment overrides the
+value that `configure' would choose:
+
+CC:      C compiler program. The default is `cc'.
+
+INSTALL: Program used to install files. The default value is `install'
+         if you have it, otherwise `cp'.
+
+For these variables, any value given in the environment is added to the
+value that `configure' chooses:
+
+DEFS:    Configuration options, in the form `-Dfoo -Dbar ...'.
+
+LIBS:    Libraries to link with, in the form `-lfoo -lbar ...'.
+
+Checking the package
+--------------------
+To check the package, i.e. to run some tests included in the package,
+you can use the following command:
+
+      make check
+
+Installing the package
+----------------------
+Normally, to install the GLPK package you should type the following
+command:
+
+      make install
+
+By default, `make install' will install the package's files in
+`usr/local/bin', `usr/local/lib', etc. You can specify an installation
+prefix other than `/usr/local' by giving `configure' the option
+`--prefix=PATH'. Alternately, you can do so by consistently giving a
+value for the `prefix' variable when you run `make', e.g.
+
+      make prefix=/usr/gnu
+      make prefix=/usr/gnu install
+
+After installing you can remove the program binaries and object files
+from the source directory by typing `make clean'. To remove all files
+that `configure' created (`Makefile', `config.status', etc.), just type
+`make distclean'.
+
+The file `configure.ac' is used to create `configure' by a program
+called `autoconf'. You only need it if you want to remake `configure'
+using a newer version of `autoconf'.
+
+Uninstalling the package
+------------------------
+To uninstall the GLPK package, i.e. to remove all the package's files
+from the system places, you can use the following command:
+
+      make uninstall

+
+The GLPK package is a set of routines written in ANSI C and organized
+in the form of a callable library. This package is intended for solving
+large-scale linear programming (LP), mixed integer linear programming
+(MIP), and other related problems.
+
+The GLPK package includes the following main components:
+
+* implementation of the simplex method;
+* implementation of the exact simplex method based on bignum (rational)
+  arithmetic;
+* implementation of the primal-dual interior-point method;
+* implementation of the branch-and-cut method;
+* application program interface (API);
+* GNU MathProg modeling language (a subset of AMPL);
+* GLPSOL, a stand-alone LP/MIP solver.
+
+See GLPK webpage <http://www.gnu.org/software/glpk/glpk.html>.
+
+Please report bugs to <bug-glpk@gnu.org>.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#

+\section{Introduction}
+
+The {\it Satisfiability Problem (SAT)} is a classic combinatorial
+problem. Given a Boolean formula of $n$ variables
+$$f(x_1,x_2,\dots,x_n),\eqno(1.1)$$
+this problem is to find such values of the variables, on which the
+formula takes on the value {\it true}.
+
+The {\it CNF Satisfiability Problem (CNF-SAT)} is a version of the
+Satisfiability Problem, where the Boolean formula (1.1) is specified
+in the {\it Conjunctive Normal Form (CNF)}, that means that it is a
+conjunction of {\it clauses}, where a clause is a disjunction of
+{\it literals}, and a literal is a variable or its negation.
+For example:
+$$(x_1\vee x_2)\;\&\;(\neg x_2\vee x_3\vee\neg x_4)\;\&\;(\neg
+x_1\vee x_4).\eqno(1.2)$$
+Here $x_1$, $x_2$, $x_3$, $x_4$ are Boolean variables to be assigned,
+$\neg$ means
+negation (logical {\it not}), $\vee$ means disjunction (logical
+{\it or}), and $\&$ means conjunction (logical {\it and}). One may
+note that the formula (1.2) is {\it satisfiable}, because on
+$x_1$ = {\it true}, $x_2$ = {\it false}, $x_3$ = {\it false}, and
+$x_4$ = {\it true} it takes on the value {\it true}. If a formula
+is not satisfiable, it is called {\it unsatisfiable}, that means that
+it takes on the value {\it false} on any values of its variables.
+
+Any CNF-SAT problem can be easily translated to a 0-1 programming
+problem as follows.\linebreak A Boolean variable $x$ can be modeled by
+a binary variable in a natural way: $x=1$ means that $x$ takes on the
+value {\it true}, and $x=0$ means that $x$ takes on the value
+{\it false}. Then, if a literal is a negated variable, i.e. $t=\neg x$,
+it can be expressed as $t=1-x$. Since a formula in CNF is a conjunction
+of clauses, to provide its satisfiability we should require all its
+clauses to  take on the value {\it true}. A particular clause is
+a disjunction of literals:
+$$t\vee t'\vee t''\dots ,\eqno(1.3)$$
+so it takes on the value {\it true} iff at least one of its literals
+takes on the value {\it true}, that can be expressed as the following
+inequality constraint:
+$$t+t'+t''+\dots\geq 1.\eqno(1.4)$$
+Note that no objective function is used in this case, because only
+a feasible solution needs to be found.
+
+For example, the formula (1.2) can be translated to the following
+constraints:
+$$\begin{array}{c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c}
+x_1&+&x_2&&&&&\geq&1\\
+&&(1-x_2)&+&x_3&+&(1-x_4)&\geq&1\\
+(1-x_1)&&&&&+&x_4&\geq&1\\
+\end{array}$$
+$$x_1, x_2, x_3, x_4\in\{0,1\}$$
+Carrying out all constant terms to the right-hand side gives
+corresponding 0-1 programming problem in the standard format:
+$$\begin{array}{r@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }c@{\ }r}
+x_1&+&x_2&&&&&\geq&1\\
+&-&x_2&+&x_3&-&x_4&\geq&-1\\
+-x_1&&&&&+&x_4&\geq&0\\
+\end{array}$$
+$$x_1, x_2, x_3, x_4\in\{0,1\}$$
+
+In general case translation of a CNF-SAT problem results in the

+\ \ \ i=1,\dots,m\eqno(1.5)$$
+$$x_j\in\{0,1\},\ \ \ j=1,\dots,n\eqno(1.6)$$
+where $n$ is the number of variables, $m$ is the number of clauses
+(inequality constraints),\linebreak $J^+_i\subseteq\{1,\dots,n\}$ is
+a subset of variables, whose literals in $i$-th clause do not have
+negation, and $J^-_i\subseteq\{1,\dots,n\}$ is a subset of variables,
+whose literals in $i$-th clause are negations of that variables. It is

+\begin{verbatim}
+   int glp_read_cnfsat(glp_prob *P, const char *fname);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_read_cnfsat| reads the CNF-SAT problem data from
+a text file in DIMACS format and automatically translates the data to
+corresponding 0-1 programming problem instance (1.5)--(1.6).
+
+The parameter \verb|P| specifies the problem object, to which the
+0-1 programming problem instance should be stored. Note that before
+reading data the current content of the problem object is completely
+erased with the routine \verb|glp_erase_prob|.
+
+The character string \verb|fname| specifies the name of a text file
+to be read in. (If the file name ends with the suffix `\verb|.gz|',
+the file is assumed to be compressed, in which case the routine
+decompresses it ``on the fly''.)
+
+\newpage
+
+\returns
+
+If the operation was successful, the routine returns zero. Otherwise,
+it prints an error message and returns non-zero.
+
+\para{DIMACS CNF-SAT problem format}\footnote{This material is based on
+the paper ``Satisfiability Suggested Format'', which is publicly
+available at {\tt http://dimacs.rutgers.edu/}.}
+
+The DIMACS input file is a plain ASCII text file. It contains lines of
+several types described below. A line is terminated with an end-of-line
+character. Fields in each line are separated by at least one blank
+space.
+
+\para{Comment lines.} Comment lines give human-readable information
+about the file and are ignored by programs. Comment lines can appear
+anywhere in the file. Each comment line begins with a lower-case
+character \verb|c|.
+
+\begin{verbatim}
+   c This is a comment line
+\end{verbatim}
+
+\para{Problem line.} There is one problem line per data file. The
+problem line must appear before any clause lines. It has the following
+format:
+
+\begin{verbatim}
+   p cnf VARIABLES CLAUSES
+\end{verbatim}
+
+\noindent
+The lower-case character \verb|p| signifies that this is a problem
+line. The three character problem designator \verb|cnf| identifies the
+file as containing specification information for the CNF-SAT problem.
+The \verb|VARIABLES| field contains an integer value specifying $n$,
+the number of variables in the instance. The \verb|CLAUSES| field
+contains an integer value specifying $m$, the number of clauses in the
+instance.
+
+\para{Clauses.} The clauses appear immediately after the problem
+line. The variables are assumed to be numbered from 1 up to $n$. It is
+not necessary that every variable appears in the instance. Each clause
+is represented by a sequence of numbers separated by either a space,
+tab, or new-line character. The non-negated version of a variable $j$
+is represented by $j$; the negated version is represented by $-j$. Each
+clause is terminated by the value 0. Unlike many formats that represent
+the end of a clause by a new-line character, this format allows clauses
+to be on multiple lines.
+
+\para{Example.} Below here is an example of the data file in DIMACS
+format corresponding to the CNF-SAT problem (1.2).

+MiniSat solver}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_minisat1(glp_prob *P);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_minisat1| is a driver to MiniSat, a CNF-SAT
+solver developed by Niklas E\'en and Niklas S\"orensson, Chalmers
+University of Technology, Sweden.\footnote{The MiniSat software module
+is {\it not} part of GLPK, but is used with GLPK and included in the
+distribution.}
+
+\newpage
+
+It is assumed that the specified problem object \verb|P| contains
+a 0-1 programming problem instance in the format (1.5)--(1.6) and
+therefore encodes a CNF-SAT problem instance.
+
+If the problem instance has been successfully solved to the end, the
+routine \verb|glp_minisat1| returns 0. In this case the routine
+\verb|glp_mip_status| can be used to determine the solution status:
+
+\begin{itemize}
+\item {\tt GLP\_OPT} means that the solver found an integer feasible
+solution and therefore the corresponding CNF-SAT instance is
+satisfiable;
+
+\item {\tt GLP\_NOFEAS} means that no integer feasible solution exists
+and therefore the corresponding CNF-SAT instance is unsatisfiable.
+\end{itemize}
+
+If an integer feasible solution was found, corresponding values of
+binary variables can be retrieved with the routine
+\verb|glp_mip_col_val|.
+
+\returns
+
+\begin{retlist}
+0 & The MIP problem instance has been successfully solved. (This code
+does {\it not} necessarily mean that the solver has found feasible
+solution. It only means that the solution process was successful.)\\
+
+{\tt GLP\_EDATA} & The specified problem object contains a MIP
+instance which does {\it not} have the format (1.5)--(1.6).\\

+\subsection{glp\_intfeas1 --- solve integer feasibility problem}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_intfeas1(glp_prob *P, int use_bound, int obj_bound);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_intfeas1| is a tentative implementation of
+an integer feasibility solver based on a CNF-SAT solver (currently
+it is MiniSat; see Subsection 2.4).
+
+If the parameter \verb|use_bound| is zero, the routine searches for
+{\it any} integer feasibile solution to the specified integer
+programming problem. Note that in this case the objective function is
+ignored.
+
+If the parameter \verb|use_bound| is non-zero, the routine searches for
+an integer feasible solution, which provides a value of the objective
+function not worse than \verb|obj_bound|. In other word, the parameter
+\verb|obj_bound| specifies an upper (in case of minimization) or lower
+(in case of maximization) bound to the objective function.
+
+If the specified problem has been successfully solved to the end, the
+routine \verb|glp_intfeas1| returns 0. In this case the routine
+\verb|glp_mip_status| can be used to determine the solution status:
+
+\begin{itemize}
+\item {\tt GLP\_FEAS} means that the solver found an integer feasible
+solution;
+
+\item {\tt GLP\_NOFEAS} means that the problem has no integer feasible
+solution (if {\tt use\_bound} is zero) or it has no integer feasible
+solution, which is not worse than {\tt obj\_bound} (if {\tt use\_bound}
+is non-zero).
+\end{itemize}
+
+\newpage
+
+If an integer feasible solution was found, corresponding values of
+variables (columns) can be retrieved with the routine
+\verb|glp_mip_col_val|.
+
+\para{Usage Notes}
+
+The integer programming problem specified by the parameter \verb|P|
+should satisfy to the following requirements:
+
+\begin{enumerate}
+\item All variables (columns) should be either binary ({\tt GLP\_BV})
+or fixed at integer values ({\tt GLP\_FX}).
+
+\item All constraint and objective coefficients should be integer
+numbers in the range\linebreak $[-2^{31},\ +2^{31}-1]$.
+\end{enumerate}
+
+Though there are no special requirements to the constraints,
+currently the routine \verb|glp_intfeas1| is efficient mainly for
+problems, where most constraints (rows) fall into the following three
+classes:
+
+\begin{enumerate}
+\item Covering inequalities
+$$\sum_{j}t_j\geq 1,$$
+where $t_j=x_j$ or $t_j=1-x_j$, $x_j$ is a binary variable.
+
+\item Packing inequalities
+$$\sum_{j}t_j\leq 1.$$
+
+\item Partitioning equalities (SOS1 constraints)
+$$\sum_{j}t_j=1.$$
+\end{enumerate}
+
+\returns
+
+\begin{retlist}
+0 & The problem has been successfully solved. (This code does
+{\it not} necessarily mean that the solver has found an integer
+feasible solution. It only means that the solution process was
+successful.) \\
+
+{\tt GLP\_EDATA} & The specified problem object does not satisfy
+to the requirements listed in Paragraph `Usage Notes'. \\
+
+{\tt GLP\_ERANGE} & An integer overflow occured on translating the
+specified problem to a CNF-SAT problem. \\
+
+{\tt GLP\_EFAIL} & The solution process was unsuccessful because of
+the solver failure. \\

+\chapter{Introduction}
+
+GLPK (\underline{G}NU \underline{L}inear \underline{P}rogramming
+\underline{K}it) is a set of routines written in the ANSI C programming
+language and organized in the form of a callable library. It is
+intended for solving linear programming (LP), mixed integer programming
+(MIP), and other related problems.
+
+\section{LP problem}
+\label{seclp}
+
+GLPK assumes the following formulation of {\it linear programming (LP)}
+problem:
+
+\medskip\noindent
+\hspace{.5in} minimize (or maximize)
+$$z = c_1x_{m+1} + c_2x_{m+2} + \dots + c_nx_{m+n} + c_0 \eqno (1.1)$$
+\hspace{.5in} subject to linear constraints
+$$
+\begin{array}{r@{\:}c@{\:}r@{\:}c@{\:}r@{\:}c@{\:}r}
+x_1&=&a_{11}x_{m+1}&+&a_{12}x_{m+2}&+ \dots +&a_{1n}x_{m+n} \\
+x_2&=&a_{21}x_{m+1}&+&a_{22}x_{m+2}&+ \dots +&a_{2n}x_{m+n} \\
+\multicolumn{7}{c}
+{.\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .\ \ .} \\
+x_m&=&a_{m1}x_{m+1}&+&a_{m2}x_{m+2}&+ \dots +&a_{mn}x_{m+n} \\
+\end{array} \eqno (1.2)
+$$
+\hspace{.5in} and bounds of variables
+$$
+\begin{array}{r@{\:}c@{\:}c@{\:}c@{\:}l}
+l_1&\leq&x_1&\leq&u_1 \\
+l_2&\leq&x_2&\leq&u_2 \\
+\multicolumn{5}{c}{.\ \ .\ \ .\ \ .\ \ .}\\
+l_{m+n}&\leq&x_{m+n}&\leq&u_{m+n} \\
+\end{array} \eqno (1.3)
+$$
+
+\medskip\noindent
+where: $x_1, x_2, \dots, x_m$ are auxiliary variables;
+$x_{m+1}, x_{m+2}, \dots, x_{m+n}$ are structural variables;
+$z$ is the objective function;
+$c_1, c_2, \dots, c_n$ are objective coefficients;
+$c_0$ is the constant term (``shift'') of the objective function;
+$a_{11}, a_{12}, \dots, a_{mn}$ are constraint coefficients;
+$l_1, l_2, \dots, l_{m+n}$ are lower bounds of variables;
+$u_1, u_2, \dots, u_{m+n}$ are upper bounds of variables.
+
+Auxiliary variables are also called {\it rows}, because they correspond
+to rows of the constraint matrix (i.e. a matrix built of the constraint
+coefficients). Similarly, structural variables are also called
+{\it columns}, because they correspond to columns of the constraint
+matrix.
+
+Bounds of variables can be finite as well as infinite. Besides, lower
+and upper bounds can be equal to each other. Thus, the following types
+of variables are possible:
+
+\begin{center}
+\begin{tabular}{r@{}c@{}ll}
+\multicolumn{3}{c}{Bounds of variable} & Type of variable \\
+\hline
+$-\infty <$ &$\ x_k\ $& $< +\infty$ & Free (unbounded) variable \\
+$l_k \leq$ &$\ x_k\ $& $< +\infty$  & Variable with lower bound \\
+$-\infty <$ &$\ x_k\ $& $\leq u_k$  & Variable with upper bound \\
+$l_k \leq$ &$\ x_k\ $& $\leq u_k$   & Double-bounded variable \\
+$l_k =$ &$\ x_k\ $& $= u_k$         & Fixed variable \\
+\end{tabular}
+\end{center}
+
+\noindent
+Note that the types of variables shown above are applicable to
+structural as well as to auxiliary variables.
+
+To solve the LP problem (1.1)---(1.3) is to find such values of all
+structural and auxiliary variables, which:
+
+\vspace*{-10pt}
+
+\begin{itemize}\setlength{\itemsep}{0pt}
+\item satisfy to all the linear constraints (1.2), and
+
+\item are within their bounds (1.3), and
+
+\item provide smallest (in case of minimization) or largest (in case of
+maximization) value of the objective function (1.1).
+\end{itemize}
+
+\section{MIP problem}
+
+{\it Mixed integer linear programming (MIP)} problem is an LP problem
+in which some variables are additionally required to be integer.
+
+GLPK assumes that MIP problem has the same formulation as ordinary
+(pure) LP problem (1.1)---(1.3), i.e. includes auxiliary and structural
+variables, which may have lower and/or upper bounds. However, in case
+of MIP problem some variables may be required to be integer. This
+additional constraint means that a value of each {\it integer variable}
+must be only integer number. (Should note that GLPK allows only
+structural variables to be of integer kind.)
+
+\section{Using the package}
+
+\subsection{Brief example}
+
+In order to understand what GLPK is from the user's standpoint,
+consider the following simple LP problem:
+
+\medskip
+
+\noindent
+\hspace{.5in} maximize
+$$z = 10 x_1 + 6 x_2 + 4 x_3$$
+\hspace{.5in} subject to
+$$
+\begin{array}{r@{\:}c@{\:}r@{\:}c@{\:}r@{\:}c@{\:}r}
+x_1 &+&x_2 &+&x_3 &\leq 100 \\
+10 x_1 &+& 4 x_2 & +&5 x_3 & \leq 600 \\
+2 x_1 &+& 2 x_2 & +& 6 x_3 & \leq 300 \\
+\end{array}
+$$
+\hspace{.5in} where all variables are non-negative
+$$x_1 \geq 0, \ x_2 \geq 0, \ x_3 \geq 0$$
+
+At first, this LP problem should be transformed to the standard form
+(1.1)---(1.3). This can be easily done by introducing auxiliary
+variables, by one for each original inequality constraint. Thus, the
+problem can be reformulated as follows:
+
+\medskip
+
+\noindent
+\hspace{.5in} maximize
+$$z = 10 x_1 + 6 x_2 + 4 x_3$$
+\hspace{.5in} subject to
+$$
+\begin{array}{r@{\:}c@{\:}r@{\:}c@{\:}r@{\:}c@{\:}r}
+p& = &x_1 &+&x_2 &+&x_3 \\
+q& = &10 x_1 &+& 4 x_2 &+& 5 x_3 \\
+r& = &2  x_1 &+& 2 x_2 &+& 6 x_3 \\
+\end{array}
+$$
+\hspace{.5in} and bounds of variables
+$$
+\begin{array}{ccc}
+\nonumber -\infty < p \leq 100 && 0 \leq x_1 < +\infty \\
+\nonumber -\infty < q \leq 600 && 0 \leq x_2 < +\infty \\
+\nonumber -\infty < r \leq 300 && 0 \leq x_3 < +\infty \\
+\end{array}
+$$
+
+\medskip
+
+where $p, q, r$ are auxiliary variables (rows), and $x_1, x_2, x_3$ are
+structural variables (columns).
+
+The example C program shown below uses GLPK API routines in order to
+solve this LP problem.\footnote{If you just need to solve LP or MIP
+instance, you may write it in MPS or CPLEX LP format and then use the
+GLPK stand-alone solver to obtain a solution. This is much less
+time-consuming than programming in C with GLPK API routines.}

+
+The statement \verb|s1| creates a problem object. Being created the
+object is initially empty. The statement \verb|s2| assigns a symbolic
+name to the problem object.
+
+The statement \verb|s3| calls the routine \verb|glp_set_obj_dir| in
+order to set the optimization direction flag, where \verb|GLP_MAX|
+means maximization.
+
+The statement \verb|s4| adds three rows to the problem object.
+
+The statement \verb|s5| assigns the symbolic name `\verb|p|' to the
+first row, and the statement \verb|s6| sets the type and bounds of the
+first row, where \verb|GLP_UP| means that the row has an upper bound.
+The statements \verb|s7|, \verb|s8|, \verb|s9|, \verb|s10| are used in
+the same way in order to assign the symbolic names `\verb|q|' and
+`\verb|r|' to the second and third rows and set their types and bounds.
+
+The statement \verb|s11| adds three columns to the problem object.
+
+The statement \verb|s12| assigns the symbolic name `\verb|x1|' to the
+first column, the statement \verb|s13| sets the type and bounds of the
+first column, where \verb|GLP_LO| means that the column has an lower
+bound, and the statement \verb|s14| sets the objective coefficient for
+the first column. The statements \verb|s15|---\verb|s20| are used in
+the same way in order to assign the symbolic names `\verb|x2|' and
+`\verb|x3|' to the second and third columns and set their types,
+bounds, and objective coefficients.
+
+The statements \verb|s21|---\verb|s29| prepare non-zero elements of the
+constraint matrix (i.e. constraint coefficients). Row indices of each
+element are stored in the array \verb|ia|, column indices are stored in
+the array \verb|ja|, and numerical values of corresponding elements are
+stored in the array \verb|ar|. Then the statement \verb|s30| calls
+the routine \verb|glp_load_matrix|, which loads information from these
+three arrays into the problem object.
+
+Now all data have been entered into the problem object, and therefore
+the statement \verb|s31| calls the routine \verb|glp_simplex|, which is
+a driver to the simplex method, in order to solve the LP problem. This
+routine finds an optimal solution and stores all relevant information
+back into the problem object.
+
+The statement \verb|s32| obtains a computed value of the objective
+function, and the statements \verb|s33|---\verb|s35| obtain computed
+values of structural variables (columns), which correspond to the
+optimal basic solution found by the solver.
+
+The statement \verb|s36| writes the optimal solution to the standard

+
+z = 733.333; x1 = 33.3333; x2 = 66.6667; x3 = 0
+\end{verbatim}
+\end{footnotesize}
+
+Finally, the statement \verb|s37| calls the routine
+\verb|glp_delete_prob|, which frees all the memory allocated to the
+problem object.
+
+\subsection{Compiling}
+
+The GLPK package has the only header file \verb|glpk.h|, which should
+be available on compiling a C (or C++) program using GLPK API routines.
+
+If the header file is installed in the default location
+\verb|/usr/local/include|, the following typical command may be used to
+compile, say, the example C program described above with the GNU C
+compiler:
+
+\begin{verbatim}
+   $ gcc -c sample.c
+\end{verbatim}
+
+If \verb|glpk.h| is not in the default location, the corresponding
+directory containing it should be made known to the C compiler through
+\verb|-I| option, for example:
+
+\begin{verbatim}
+   $ gcc -I/foo/bar/glpk-4.15/include -c sample.c
+\end{verbatim}
+
+In any case the compilation results in an object file \verb|sample.o|.
+
+\subsection{Linking}
+
+The GLPK library is a single file \verb|libglpk.a|. (On systems which
+support shared libraries there may be also a shared version of the
+library \verb|libglpk.so|.)
+
+If the library is installed in the default
+location \verb|/usr/local/lib|, the following typical command may be
+used to link, say, the example C program described above against with
+the library:
+
+\begin{verbatim}
+   $ gcc sample.o -lglpk -lm
+\end{verbatim}
+
+If the GLPK library is not in the default location, the corresponding
+directory containing it should be made known to the linker through
+\verb|-L| option, for example:
+
+\begin{verbatim}
+   $ gcc -L/foo/bar/glpk-4.15 sample.o -lglpk -lm
+\end{verbatim}
+
+Depending on configuration of the package linking against with the GLPK
+library may require optional libraries, in which case these libraries
+should be also made known to the linker, for example:
+
+\begin{verbatim}
+   $ gcc sample.o -lglpk -lgmp -lm
+\end{verbatim}
+
+For more details about configuration options of the GLPK package see
+Appendix \ref{install}, page \pageref{install}.

+\subsection{glp\_init\_env --- initialize GLPK environment}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_init_env(void);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_init_env| initializes the GLPK environment.
+Normally the application program does not need to call this routine,
+because it is called automatically on the first call to any API
+routine.
+
+\returns
+
+\begin{retlist}
+0 & initialization successful;\\
+1 & environment is already initialized;\\
+2 & initialization failed (insufficient memory);\\
+3 & initialization failed (unsupported programming model).\\
+\end{retlist}
+
+\subsection{glp\_version --- determine library version}
+
+\synopsis
+
+\begin{verbatim}
+   const char *glp_version(void);
+\end{verbatim}
+
+\returns
+
+The routine \verb|glp_version| returns a pointer to a null-terminated
+character string, which specifies the version of the GLPK library in
+the form \verb|"X.Y"|, where `\verb|X|' is the major version number,
+and `\verb|Y|' is the minor version number, for example, \verb|"4.16"|.

+\subsection{glp\_free\_env --- free GLPK environment}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_free_env(void);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_free_env| frees all resources used by GLPK
+routines (memory blocks, etc.) which are currently still in use.
+
+Normally the application program does not need to call this routine,
+because GLPK routines always free all unused resources. However, if
+the application program even has deleted all problem objects, there
+will be several memory blocks still allocated for the internal library
+needs. For some reasons the application program may want GLPK to free
+this memory, in which case it should call \verb|glp_free_env|.
+
+Note that a call to \verb|glp_free_env| invalidates all problem objects
+which still exist.
+
+\returns
+
+\begin{retlist}
+0 & termination successful;\\
+1 & environment is inactive (was not initialized).\\

+\subsection{glp\_printf --- write formatted output to terminal}
+
+\synopsis
+
+\begin{verbatim}
+   void glp_printf(const char *fmt, ...);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_printf| uses the format control string
+\verb|fmt| to format its parameters and writes the formatted output to
+the terminal.
+
+This routine is a replacement of the standard C function
+\verb|printf| and used by all GLPK routines to perform terminal
+output. The application program may use \verb|glp_printf| for the same
+purpose that allows controlling its terminal output with the routines
+\verb|glp_term_out| and \verb|glp_term_hook|.

+\verb|fmt| to format its parameters specified by the list \verb|arg|
+and writes the formatted output to the terminal.
+
+This routine is a replacement of the standard C function
+\verb|vprintf| and used by all GLPK routines to perform terminal
+output. The application program may use \verb|glp_vprintf| for the same
+purpose that allows controlling its terminal output with the routines

+\subsection{glp\_term\_out --- enable/disable terminal output}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_term_out(int flag);
+\end{verbatim}
+
+\description
+
+Depending on the parameter flag the routine \verb|glp_term_out| enables
+or disables terminal output performed by glpk routines:
+
+\verb|GLP_ON | --- enable terminal output;
+
+\verb|GLP_OFF| --- disable terminal output.
+
+\returns
+
+The routine \verb|glp_term_out| returns the previous value of the
+terminal output flag.
+
+\subsection{glp\_term\_hook --- intercept terminal output}
+
+\synopsis
+
+\begin{verbatim}
+   void glp_term_hook(int (*func)(void *info, const char *s), void *info);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_term_hook| installs the user-defined hook routine
+to intercept all terminal output performed by GLPK routines.
+
+%This feature can be used to redirect the terminal output to other
+%destination, for example, to a file or a text window.
+
+The parameter {\it func} specifies the user-defined hook routine. It is
+called from an internal printing routine, which passes to it two
+parameters: {\it info} and {\it s}. The parameter {\it info} is a
+transit pointer specified in corresponding call to the routine
+\verb|glp_term_hook|; it may be used to pass some additional information
+to the hook routine. The parameter {\it s} is a pointer to the null
+terminated character string, which is intended to be written to the
+terminal. If the hook routine returns zero, the printing routine writes
+the string {\it s} to the terminal in a usual way; otherwise, if the
+hook routine returns non-zero, no terminal output is performed.
+
+To uninstall the hook routine both parameters {\it func} and {\it info}
+should be specified as \verb|NULL|.
+
+\para{Example}
+
+\begin{footnotesize}
+\begin{verbatim}
+static int hook(void *info, const char *s)

+
+\description
+
+The routine \verb|glp_open_tee| starts copying all the terminal output
+to an output text file, whose name is specified by the character string
+\verb|fname|.
+
+\returns
+
+\begin{retlist}
+0 & operation successful;\\

+\end{verbatim}
+
+\description
+
+The routine \verb|glp_close_tee| stops copying the terminal output to

+\newpage
+
+\subsection{glp\_at\_error --- check for error state}
+
+\synopsis
+
+\begin{verbatim}
+   int glp_at_error(void);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_at_error| checks if the GLPK environment is at
+error state, i.~e.~if the call to the routine is (indirectly) made from
+the \verb|glp_error| routine via an user-defined hook routine.
+
+This routine can be used, for example, by a custom output handler
+(installed with the routine \verb|glp_term_hook|) to determine whether
+or not the message to be displayed is an error message.
+
+\returns
+
+If the GLPK environment is at error state, the routine returns
+non-zero, otherwise zero.
+
+\subsection{glp\_assert --- check logical condition}
+
+\synopsis
+
+\begin{verbatim}
+   void glp_assert(int expr);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_assert| (implemented as a macro) checks
+a logical condition specified by the expression \verb|expr|. If the
+condition is true (non-zero), the routine does nothing; otherwise, if
+the condition is false (zero), the routine prints an error message and
+abnormally terminates the program.
+
+This routine is a replacement of the standard C function \verb|assert|
+and used by all GLPK routines to check program logic. The application
+program may use \verb|glp_assert| for the same purpose.

+\subsection{glp\_error\_hook --- install hook to intercept abnormal
+termination}
+
+\synopsis
+
+\begin{verbatim}
+   void glp_error_hook(void (*func)(void *info), void *info);
+\end{verbatim}
+
+\description
+
+The routine \verb|glp_error_hook| installs a user-defined hook routine
+to intercept abnormal termination.
+
+The parameter \verb|func| specifies the user-defined hook routine. It
+is called from the routine \verb|glp_error| before the latter calls the
+abort function to abnormally terminate the application program because
+of fatal error. The parameter \verb|info| is a transit pointer,
+specified in the corresponding call to the routine
+\verb|glp_error_hook|; it may be used to pass some information to the
+hook routine.
+
+To uninstall the hook routine the parameters \verb|func| and \verb|info|
+should be specified as \verb|NULL|.
+
+If the hook routine returns, the application program is abnormally
+terminated. To prevent abnormal termnation the hook routine may perform
+a global jump using the standard function \verb|longjmp|, in which case
+the application program {\it must} call the routine \verb|glp_free_env|.

+
+1) the parameters \verb|n| and \verb|size| must be positive;
+
+2) having been allocated the memory block contains arbitrary data, that
+is, it is {\it not} initialized by binary zeros;
+
+3) if the block cannot be allocated due to insufficient memory, the

+
+This routine is a replacement of the standard C function \verb|malloc|
+and used by GLPK routines for dynamic memory allocation. The
+application program may use \verb|glp_alloc| for the same purpose.
+
+\returns
+
+The routine \verb|glp_alloc| returns a pointer to the memory block
+allocated. To free this block the routine \verb|glp_free| (not the

+The routine \verb|glp_realloc| dynamically reallocates a memory block
+pointed to by \verb|ptr|, which was previously allocated by the routine
+\verb|glp_alloc| or reallocated by this routine. Note that the pointer
+\verb|ptr| must be valid and must not be \verb|NULL|. The new size of

+\chapter{Installing GLPK on Your Computer}
+\label{install}
+
+\section{Downloading the distribution tarball}
+
+The distribution tarball of the most recent version of the GLPK
+package can be found on \url{http://ftp.gnu.org/gnu/glpk/} [via http]
+and \url{ftp://ftp.gnu.org/gnu/glpk/} [via FTP]. It can also be found
+on one of the FTP mirrors; see \url{http://www.gnu.org/prep/ftp.html}.
+Please use a mirror if possible.
+
+To make sure that the GLPK distribution tarball you have downloaded is
+intact you need to download the corresponding `\verb|.sig|' file and
+run a command like this:
+
+\begin{verbatim}
+   gpg --verify glpk-4.38.tar.gz.sig
+\end{verbatim}
+
+\noindent
+If that command fails because you do not have the required public key,
+run the following command to import it:
+
+\begin{verbatim}
+   gpg --keyserver keys.gnupg.net --recv-keys 5981E818
+\end{verbatim}
+
+\noindent
+and then re-run the previous command.
+
+\section{Unpacking the distribution tarball}
+
+The GLPK package (like all other GNU software) is distributed in the
+form of packed archive. This is one file named \verb|glpk-X.Y.tar.gz|,
+where {\it X} is the major version number and {\it Y} is the minor
+version number.
+
+In order to prepare the distribution for installation you need to copy
+the GLPK distribution file to a working subdirectory and then unpack
+and unarchive the distribution file with the following command:
+
+\begin{verbatim}
+   tar zx < glpk-X.Y.tar
+\end{verbatim}
+
+\newpage
+
+\section{Configuring the package}
+
+After unpacking and unarchiving the GLPK distribution you should
+configure the package,\linebreak i.e. automatically tune it for your
+platform.
+
+Normally, you should just \verb|cd| to the subdirectory \verb|glpk-X.Y|
+and run the configure script, e.g.
+
+\begin{verbatim}
+   ./configure
+\end{verbatim}
+
+The `\verb|configure|' shell script attempts to guess correct values
+for various system-dependent variables used during compilation. It uses
+those values to create a `\verb|Makefile|' in each directory of the
+package. It also creates file `\verb|config.h|' containing
+platform-dependent definitions. Finally, it creates a shell script
+`\verb|config.status|' that you can run in the future to recreate the
+current configuration, a file `\verb|config.cache|' that saves the
+results of its tests to speed up reconfiguring, and a file
+`\verb|config.log|' containing compiler output (useful mainly for
+debugging `\verb|configure|').
+
+Running `\verb|configure|' takes about a minute. While it is running,
+it displays some informational messages that tell you what it
+is doing. If you don't want to see these messages, run
+`\verb|configure|' with its standard output redirected to
+`\verb|dev/null|'; for example, `\verb|./configure > /dev/null|'.
+
+By default both static and shared versions of the GLPK library will be
+compiled. Compilation of the shared librariy can be turned off by
+specifying the `\verb|--disable-shared|' option to `\verb|configure|':
+
+\begin{verbatim}
+   ./configure --disable-shared
+\end{verbatim}
+
+\noindent
+If you encounter problems building the library try using the above
+option, because some platforms do not support shared libraries.
+
+The GLPK package has some optional features listed below. By default
+all these features are disabled. To enable a feature the corresponding
+option should be passed to the configure script.
+
+\verb|--with-gmp         | Enable using the GNU MP bignum library
+
+This feature allows the exact simplex solver to use the GNU MP bignum

+
+\section{Compiling the package}
+
+Normally, you can compile (build) the package by typing the command:
+
+\begin{verbatim}
+   make
+\end{verbatim}
+
+\noindent
+It reads `\verb|Makefile|' generated by `\verb|configure|' and performs
+all necessary jobs.
+
+If you want, you can override the `\verb|make|' variables \verb|CFLAGS|
+and \verb|LDFLAGS| like this:
+
+\begin{verbatim}
+   make CFLAGS=-O2 LDFLAGS=-s
+\end{verbatim}
+
+To compile the package in a different directory from the one containing
+the source code, you must use a version of `\verb|make|' that supports
+`\verb|VPATH|' variable, such as GNU `\verb|make|'. `\verb|cd|' to the
+directory where you want the object files and executables to go and run
+the `\verb|configure|' script. `\verb|configure|' automatically checks
+for the source code in the directory that `\verb|configure|' is in and
+in `\verb|..|'. If for some reason `\verb|configure|' is not in the
+source code directory that you are configuring, then it will report
+that it can't find the source code. In that case, run `\verb|configure|'
+with the option `\verb|--srcdir=DIR|', where \verb|DIR| is the
+directory that contains the source code.
+
+Some systems require unusual options for compilation or linking that
+the `\verb|configure|' script does not know about. You can give
+`\verb|configure|' initial values for variables by setting them in the
+environment. Using a Bourne-compatible shell, you can do that on the
+command line like this:
+
+\begin{verbatim}
+   CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+\end{verbatim}
+
+\noindent
+Or on systems that have the `\verb|env|' program, you can do it like
+this:
+
+\begin{verbatim}
+   env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+\end{verbatim}
+
+Here are the `\verb|make|' variables that you might want to override
+with environment variables when running `\verb|configure|'.
+
+For these variables, any value given in the environment overrides the
+value that `\verb|configure|' would choose:
+
+\verb|CC      | C compiler program. The default is `\verb|cc|'.
+
+\verb|INSTALL | Program used to install files. The default value is
+`\verb|install|' if you have it,\\
+\verb|           | otherwise `\verb|cp|'.
+
+For these variables, any value given in the environment is added to the
+value that `\verb|configure|' chooses:
+
+\verb|DEFS    | Configuration options, in the form
+`\verb|-Dfoo -Dbar| \dots'.
+
+\verb|LIBS    | Libraries to link with, in the form
+`\verb|-lfoo -lbar| \dots'.
+
+\section{Checking the package}
+
+To check the package, i.e. to run some tests included in the package,
+you can use the following command:
+
+\begin{verbatim}
+   make check
+\end{verbatim}
+
+\section{Installing the package}
+
+Normally, to install the GLPK package you should type the following
+command:
+
+\begin{verbatim}
+   make install
+\end{verbatim}
+
+\noindent
+By default, `\verb|make install|' will install the package's files in
+`\verb|usr/local/bin|', `\verb|usr/local/lib|', etc. You can specify an
+installation prefix other than `\verb|/usr/local|' by giving
+`\verb|configure|' the option `\verb|--prefix=PATH|'. Alternately, you
+can do so by consistently giving a value for the `\verb|prefix|'
+variable when you run `\verb|make|', e.g.
+
+\begin{verbatim}
+   make prefix=/usr/gnu
+   make prefix=/usr/gnu install
+\end{verbatim}
+
+After installing you can remove the program binaries and object files
+from the source directory by typing `\verb|make clean|'. To remove all
+files that `\verb|configure|' created (`\verb|Makefile|',
+`\verb|config.status|', etc.), just type `\verb|make distclean|'.
+
+The file `\verb|configure.ac|' is used to create `\verb|configure|' by
+a program called `\verb|autoconf|'. You only need it if you want to
+remake `\verb|configure|' using a newer version of `\verb|autoconf|'.
+
+\section{Uninstalling the package}
+
+To uninstall the GLPK package, i.e. to remove all the package's files
+from the system places, you can use the following command:
+
+\begin{verbatim}
+   make uninstall
+\end{verbatim}

+\chapter{MPS Format}
+\label{champs}
+
+\section{Fixed MPS Format}
+\label{secmps}
+
+The MPS format\footnote{The MPS format was developed in 1960's by IBM
+as input format for their mathematical programming system MPS/360.
+Today the MPS format is a most widely used format understood by most
+mathematical programming packages. This appendix describes only the
+features of the MPS format, which are implemented in the GLPK package.}
+is intended for coding LP/MIP problem data. This format assumes the
+formulation of LP/MIP problem (1.1)---(1.3) (see Section \ref{seclp},
+page \pageref{seclp}).
+
+{\it MPS file} is a text file, which contains two types of
+cards\footnote{In 1960's MPS file was a deck of 80-column punched
+cards, so the author decided to keep the word ``card'', which may be
+understood as ``line of text file''.}: indicator cards and data cards.
+
+Indicator cards determine a kind of succeeding data. Each indicator
+card has one word in uppercase letters beginning in column 1.
+
+Data cards contain problem data. Each data card is divided into six
+fixed fields:
+
+\begin{center}
+\begin{tabular}{lcccccc}
+& Field 1 & Field 2 & Field 3 & Field 4 & Field 5 & Feld 6 \\
+\hline
+Columns & 2---3 & 5---12 & 15---22 & 25---36 & 40---47 & 50---61 \\
+Contents & Code & Name & Name & Number & Name & Number \\
+\end{tabular}
+\end{center}
+
+On a particular data card some fields may be optional.
+
+Names are used to identify rows, columns, and some vectors (see below).
+
+Aligning the indicator code in the field 1 to the left margin is
+optional.
+
+All names specified in the fields 2, 3, and 5 should contain from 1 up
+to 8 arbitrary characters (except control characters). If a name is
+placed in the field 3 or 5, its first character should not be the dollar
+sign `\verb|$|'. If a name contains spaces, the spaces are ignored.
+
+All numerical values in the fields 4 and 6 should be coded in the form
+$sxx$\verb|E|$syy$, where $s$ is the plus `\verb|+|' or the minus
+`\verb|-|' sign, $xx$ is a real number with optional decimal point,
+$yy$ is an integer decimal exponent. Any number should contain up to 12
+characters. If the sign $s$ is omitted, the plus sign is assumed. The
+exponent part is optional. If a number contains spaces, the spaces are
+ignored.
+
+\newpage
+
+If a card has the asterisk `\verb|*|' in the column 1, this card is
+considered as a comment and ignored. Besides, if the first character in
+the field 3 or 5 is the dollar sign `\verb|$|', all characters from the
+dollar sign to the end of card are considered as a comment and ignored.
+
+MPS file should contain cards in the following order:
+
+\vspace*{-8pt}
+
+\begin{itemize}
+\item NAME indicator card;
+
+\item ROWS indicator card;
+
+\item data cards specifying rows (constraints);
+
+\item COLUMNS indicator card;
+
+\item data cards specifying columns (structural variables) and
+constraint coefficients;
+
+\item RHS indicator card;
+
+\item data cards specifying right-hand sides of constraints;
+
+\item RANGES indicator card;
+
+\item data cards specifying ranges for double-bounded constraints;
+
+\item BOUNDS indicator card;
+
+\item data cards specifying types and bounds of structural
+variables;
+
+\item ENDATA indicator card.
+\end{itemize}
+
+\vspace*{-8pt}
+
+{\it Section} is a group of cards consisting of an indicator card and
+data cards succeeding this indicator card. For example, the ROWS section
+consists of the ROWS indicator card and data cards specifying rows.
+
+The sections RHS, RANGES, and BOUNDS are optional and may be omitted.
+
+\section{Free MPS Format}
+
+{\it Free MPS format} is an improved version of the standard (fixed)
+MPS format described above.\footnote{This format was developed in the
+beginning of 1990's by IBM as an alternative to the standard fixed MPS
+format for Optimization Subroutine Library (OSL).} Note that all
+changes in free MPS format concern only the coding of data while the
+structure of data is the same for both fixed and free versions of the
+MPS format.
+
+In free MPS format indicator and data records\footnote{{\it Record} in
+free MPS format has the same meaning as {\it card} in fixed MPS format.}
+may have arbitrary length not limited to 80 characters. Fields of data
+records have no predefined positions, i.e. the fields may begin in any
+position, except position 1, which must be blank, and must be separated
+from each other by one or more blanks. However, the fields must appear
+in the same order as in fixed MPS format.
+
+\newpage
+
+Symbolic names in fields 2, 3, and 5 may be longer than 8
+characters\footnote{GLPK allows symbolic names having up to 255
+characters.} and must not contain embedded blanks.
+
+Numeric values in fields 4 and 6 are limited to 12 characters and must
+not contain embedded blanks.
+
+Only six fields on each data record are used. Any other fields are
+ignored.
+
+If the first character of any field (not necessarily fields 3 and 5)
+is the dollar sign (\$), all characters from the dollar sign to the end
+of record are considered as a comment and ignored.
+
+\section{NAME indicator card}
+
+The NAME indicator card should be the first card in the MPS file
+(except optional comment cards, which may precede the NAME card). This
+card should contain the word \verb|NAME| in the columns 1---4 and the
+problem name in the field 3. The problem name is optional and may be
+omitted.
+
+\section{ROWS section}
+\label{secrows}
+
+The ROWS section should start with the indicator card, which contains
+the word \verb|ROWS| in the columns 1---4.
+
+Each data card in the ROWS section specifies one row (constraint) of
+the problem. All these data cards have the following format.
+
+`\verb|N|' in the field 1 means that the row is free (unbounded):
+$$-\infty < x_i = a_{i1}x_{m+1} + a_{i2}x_{m+2} + \dots + a_{in}x_{m+n}
+< +\infty;$$
+
+`\verb|L|' in the field 1 means that the row is of ``less than or equal
+to'' type:
+$$-\infty < x_i = a_{i1}x_{m+1} + a_{i2}x_{m+2} + \dots + a_{in}x_{m+n}
+\leq b_i;$$
+
+`\verb|G|' in the field 1 means that the row is of ``greater than or
+equal to'' type:
+$$b_i \leq x_i = a_{i1}x_{m+1} + a_{i2}x_{m+2} + \dots + a_{in}x_{m+n}
+< +\infty;$$
+
+`\verb|E|' in the field 1 means that the row is of ``equal to'' type:
+$$x_i = a_{i1}x_{m+1} + a_{i2}x_{m+2} + \dots + a_{in}x_{m+n} \leq
+b_i,$$
+where $b_i$ is a right-hand side. Note that each constraint has a
+corresponding implictly defined auxiliary variable ($x_i$ above), whose
+value is a value of the corresponding linear form, therefore row bounds
+can be considered as bounds of such auxiliary variable.
+
+The filed 2 specifies a row name (which is considered as the name of
+the corresponding auxiliary variable).
+
+\newpage
+
+The fields 3, 4, 5, and 6 are not used and should be empty.
+
+Numerical values of all non-zero right-hand sides $b_i$ should be
+specified in the RHS section (see below). All double-bounded (ranged)
+constraints should be specified in the RANGES section (see below).
+
+\section{COLUMNS section}
+
+The COLUMNS section should start with the indicator card, which
+contains the word \verb|COLUMNS| in the columns 1---7.
+
+Each data card in the COLUMNS section specifies one or two constraint
+coefficients $a_{ij}$ and also introduces names of columns, i.e. names
+of structural variables. All these data cards have the following
+format.
+
+The field 1 is not used and should be empty.
+
+The field 2 specifies a column name. If this field is empty, the column
+name from the immediately preceeding data card is assumed.
+
+The field 3 specifies a row name defined in the ROWS section.
+
+The field 4 specifies a numerical value of the constraint coefficient
+$a_{ij}$, which is placed in the corresponding row and column.
+
+The fields 5 and 6 are optional. If they are used, they should contain
+a second pair ``row name---constraint coefficient'' for the same column.
+
+Elements of the constraint matrix (i.e. constraint coefficients) should
+be enumerated in the column wise manner: all elements for the current
+column should be specified before elements for the next column. However,
+the order of rows in the COLUMNS section may differ from the order of
+rows in the ROWS section.
+
+Constraint coefficients not specified in the COLUMNS section are
+considered as zeros. Therefore zero coefficients may be omitted,
+although it is allowed to explicitly specify them.
+
+\section{RHS section}
+
+The RHS section should start with the indicator card, which contains the
+word \verb|RHS| in the columns 1---3.
+
+Each data card in the RHS section specifies one or two right-hand sides
+$b_i$ (see Section \ref{secrows}, page \pageref{secrows}). All these
+data cards have the following format.
+
+The field 1 is not used and should be empty.
+
+The field 2 specifies a name of the right-hand side (RHS)
+vector\footnote{This feature allows the user to specify several RHS
+vectors in the same MPS file. However, before solving the problem a
+particular RHS vector should be chosen.}. If this field is empty, the
+RHS vector name from the immediately preceeding data card is assumed.
+
+\newpage
+
+The field 3 specifies a row name defined in the ROWS section.
+
+The field 4 specifies a right-hand side $b_i$ for the row, whose name is
+specified in the field 3. Depending on the row type $b_i$ is a lower
+bound (for the row of \verb|G| type), an upper bound (for the row of
+\verb|L| type), or a fixed value (for the row of \verb|E|
+type).\footnote{If the row is of {\tt N} type, $b_i$ is considered as
+a constant term of the corresponding linear form. Should note, however,
+this convention is non-standard.}
+
+The fields 5 and 6 are optional. If they are used, they should contain
+a second pair ``row name---right-hand side'' for the same RHS vector.
+
+All right-hand sides for the current RHS vector should be specified
+before right-hand sides for the next RHS vector. However, the order of
+rows in the RHS section may differ from the order of rows in the ROWS
+section.
+
+Right-hand sides not specified in the RHS section are considered as
+zeros. Therefore zero right-hand sides may be omitted, although it is
+allowed to explicitly specify them.
+
+\section{RANGES section}
+
+The RANGES section should start with the indicator card, which contains
+the word \verb|RANGES| in the columns 1---6.
+
+Each data card in the RANGES section specifies one or two ranges for
+double-side constraints, i.e. for constraints that are of the types
+\verb|L| and \verb|G| at the same time:
+$$l_i \leq x_i = a_{i1}x_{m+1} + a_{i2}x_{m+2} + \dots + a_{in}x_{m+n}
+\leq u_i,$$
+where $l_i$ is a lower bound, $u_i$ is an upper bound. All these data
+cards have the following format.
+
+The field 1 is not used and should be empty.
+
+The field 2 specifies a name of the range vector\footnote{This feature
+allows the user to specify several range vectors in the same MPS file.
+However, before solving the problem a particular range vector should be
+chosen.}. If this field is empty, the range vector name from the
+immediately preceeding data card is assumed.
+
+The field 3 specifies a row name defined in the ROWS section.
+
+The field 4 specifies a range value $r_i$ (see the table below) for the
+row, whose name is specified in the field 3.
+
+The fields 5 and 6 are optional. If they are used, they should contain
+a second pair ``row name---range value'' for the same range vector.
+
+All range values for the current range vector should be specified before
+range values for the next range vector. However, the order of rows in
+the RANGES section may differ from the order of rows in the ROWS
+section.
+
+For each double-side constraint specified in the RANGES section its
+lower and upper bounds are determined as follows:
+
+\newpage
+
+\begin{center}
+\begin{tabular}{cccc}
+Row type & Sign of $r_i$ & Lower bound & Upper bound \\
+\hline
+{\tt G} & $+$ or $-$ & $b_i$ & $b_i + |r_i|$ \\
+{\tt L} & $+$ or $-$ & $b_i - |r_i|$ & $b_i$ \\
+{\tt E} & $+$ & $b_i$ & $b_i + |r_i|$ \\
+{\tt E} & $-$ & $b_i - |r_i|$ & $b_i$ \\
+\end{tabular}
+\end{center}
+
+\noindent
+where $b_i$ is a right-hand side specified in the RHS section (if $b_i$
+is not specified, it is considered as zero), $r_i$ is a range value
+specified in the RANGES section.
+
+\section{BOUNDS section}
+\label{secbounds}
+
+The BOUNDS section should start with the indicator card, which contains
+the word \verb|BOUNDS| in the columns 1---6.
+
+Each data card in the BOUNDS section specifies one (lower or upper)
+bound for one structural variable (column). All these data cards have
+the following format.
+
+The indicator in the field 1 specifies the bound type:
+
+\verb|LO| --- lower bound;
+
+\verb|UP| --- upper bound;
+
+\verb|FX| --- fixed variable (lower and upper bounds are equal);
+
+\verb|FR| --- free variable (no bounds);
+
+\verb|MI| --- no lower bound (lower bound is ``minus infinity'');
+
+\verb|PL| --- no upper bound (upper bound is ``plus infinity'').
+
+The field 2 specifies a name of the bound vector\footnote{This feature
+allows the user to specify several bound vectors in the same MPS file.
+However, before solving the problem a particular bound vector should be
+chosen.}. If this field is empty, the bound vector name from the
+immediately preceeding data card is assumed.
+
+The field 3 specifies a column name defined in the COLUMNS section.
+
+The field 4 specifies a bound value. If the bound type in the field 1
+differs from \verb|LO|, \verb|UP|, and \verb|FX|, the value in the field
+4 is ignored and may be omitted.
+
+The fields 5 and 6 are not used and should be empty.
+
+All bound values for the current bound vector should be specified before
+bound values for the next bound vector. However, the order of columns in
+the BOUNDS section may differ from the order of columns in the COLUMNS
+section. Specification of a lower bound should precede specification of
+an upper bound for the same column (if both the lower and upper bounds
+are explicitly specified).
+
+By default, all columns (structural variables) are non-negative, i.e.
+have zero lower bound and no upper bound. Lower ($l_j$) and upper
+($u_j$) bounds of some column (structural variable $x_j$) are set in the
+following way, where $s_j$ is a corresponding bound value explicitly
+specified in the BOUNDS section:
+
+\newpage
+
+\verb|LO| sets $l_j$ to $s_j$;
+
+\verb|UP| sets $u_j$ to $s_j$;
+
+\verb|FX| sets both $l_j$ and $u_j$ to $s_j$;
+
+\verb|FR| sets $l_j$ to $-\infty$ and $u_j$ to $+\infty$;
+
+\verb|MI| sets $l_j$ to $-\infty$;
+
+\verb|PL| sets $u_j$ to $+\infty$.
+
+\section{ENDATA indicator card}
+
+The ENDATA indicator card should be the last card of MPS file (except
+optional comment cards, which may follow the ENDATA card). This card
+should contain the word \verb|ENDATA| in the columns 1---6.
+
+\section{Specifying objective function}
+
+It is impossible to explicitly specify the objective function and
+optimization direction in the MPS file. However, the following implicit
+rule is used by default: the first row of \verb|N| type is considered
+as a row of the objective function (i.e. the objective function is the
+corresponding auxiliary variable), which should be {\it minimized}.
+
+GLPK also allows specifying a constant term of the objective function
+as a right-hand side of the corresponding row in the RHS section.
+
+\section{Example of MPS file}
+\label{secmpsex}
+
+To illustrate what the MPS format is, consider the following example of
+LP problem:
+
+\def\arraystretch{1.2}
+

+\section{MIP features}
+
+\vspace*{-4pt}
+
+The MPS format provides two ways for introducing integer variables into
+the problem.
+
+The first way is most general and based on using special marker cards
+INTORG and INTEND. These marker cards are placed in the COLUMNS section.
+The INTORG card indicates the start of a group of integer variables
+(columns), and the card INTEND indicates the end of the group. The MPS
+file may contain arbitrary number of the marker cards.
+
+The marker cards have the same format as the data cards (see Section
+\ref{secmps}, page \pageref{secmps}).
+
+The fields 1, 2, and 6 are not used and should be empty.
+
+The field 2 should contain a marker name. This name may be arbitrary.
+
+The field 3 should contain the word \verb|'MARKER'| (including
+apostrophes).
+
+The field 5 should contain either the word \verb|'INTORG'| (including
+apostrophes) for the marker card, which begins a group of integer
+columns, or the word \verb|'INTEND'| (including apostrophes) for the
+marker card, which ends the group.
+
+The second way is less general but more convenient in some cases. It
+allows the user declaring integer columns using three additional types
+of bounds, which are specified in the field 1 of data cards in the
+BOUNDS section (see Section \ref{secbounds}, page \pageref{secbounds}):
+
+\verb|LI| --- lower integer. This bound type specifies that the
+corresponding column (structural variable), whose name is specified in
+field 3, is of integer kind. In this case an lower bound of the
+column should be specified in field 4 (like in the case of \verb|LO|
+bound type).
+
+\verb|UI| --- upper integer. This bound type specifies that the
+corresponding column (structural variable), whose name is specified in
+field 3, is of integer kind. In this case an upper bound of the
+column should be specified in field 4 (like in the case of \verb|UP|
+bound type).
+
+\verb|BV| --- binary variable. This bound type specifies that the
+corresponding column (structural variable), whose name is specified in
+the field 3, is of integer kind, its lower bound is zero, and its upper
+bound is one (thus, such variable being of integer kind can have only
+two values zero and one). In this case a numeric value specified in the
+field 4 is ignored and may be omitted.
+
+Consider the following example of MIP problem:
+
+\noindent
+\hspace{1in} minimize
+$$Z = 3 x_1 + 7 x_2 - x_3 + x4$$
+\hspace{1in} subject to linear constraints
+$$
+\begin{array}{c}
+\nonumber r_1 = 2   x_1 - \ \ x_2 + \ \ x_3 - \ \;x_4 \\
+\nonumber r_2 = \ \;x_1 - \ \;x_2 - 6   x_3 + 4   x_4 \\
+\nonumber r_3 = 5   x_1 +   3 x_2 \ \ \ \ \ \ \ \ \ + \ \ x_4 \\
+\end{array}
+$$
+\hspace{1in} and bound of variables
+$$
+\begin{array}{cccl}
+\nonumber 1 \leq r_1 < +\infty && 0 \leq x_1 \leq 4 &{\rm(continuous)}\\
+\nonumber 8 \leq r_2 < +\infty && 2 \leq x_2 \leq 5 &{\rm(integer)}   \\
+\nonumber 5 \leq r_3 < +\infty && 0 \leq x_3 \leq 1 &{\rm(integer)}   \\
+\nonumber                      && 3 \leq x_4 \leq 8 &{\rm(continuous)}\\
+\end{array}
+$$
+
+The corresponding MPS file may look like the following:

+%\section{Specifying predefined basis}
+%\label{secbas}
+%
+%The MPS format can also be used to specify some predefined basis for an
+%LP problem, i.e. to specify which rows and columns are basic and which
+%are non-basic.
+%
+%The order of a basis file in the MPS format is:
+%
+%$\bullet$ NAME indicator card;
+%
+%$\bullet$ data cards (can appear in arbitrary order);
+%
+%$\bullet$ ENDATA indicator card.
+%
+%Each data card specifies either a pair "basic column---non-basic row"
+%or a non-basic column. All the data cards have the following format.
+%
+%`\verb|XL|' in the field 1 means that a column, whose name is given in
+%the field 2, is basic, and a row, whose name is given in the field 3,
+%is non-basic and placed on its lower bound.
+%
+%`\verb|XU|' in the field 1 means that a column, whose name is given in
+%the field 2, is basic, and a row, whose name is given in the field 3,
+%is non-basic and placed on its upper bound.
+%
+%`\verb|LL|' in the field 1 means that a column, whose name is given in
+%the field 3, is non-basic and placed on its lower bound.
+%
+%`\verb|UL|' in the field 1 means that a column, whose name is given in
+%the field 3, is non-basic and placed on its upper bound.
+%
+%The field 2 contains a column name.
+%
+%If the indicator given in the field 1 is `\verb|XL|' or `\verb|XU|',
+%the field 3 contains a row name. Otherwise, if the indicator is
+%`\verb|LL|' or `\verb|UL|', the field 3 is not used and should be
+%empty.
+%
+%The field 4, 5, and 6 are not used and should be empty.
+%
+%A basis file in the MPS format acts like a patch: it doesn't specify
+%a basis completely, instead that it is just shows in what a given basis
+%differs from the "standard" basis, where all rows (auxiliary variables)
+%are assumed to be basic and all columns (structural variables) are
+%assumed to be non-basic.
+%
+%As an example here is a basis file that specifies an optimal basis
+%for the example LP problem given in Section \ref{secmpsex},

+\chapter{CPLEX LP Format}
+\label{chacplex}
+
+\section{Prelude}
+
+The CPLEX LP format\footnote{The CPLEX LP format was developed in
+the end of 1980's by CPLEX Optimization, Inc. as an input format for
+the CPLEX linear programming system. Although the CPLEX LP format is
+not as widely used as the MPS format, being row-oriented it is more
+convenient for coding mathematical programming models by human. This
+appendix describes only the features of the CPLEX LP format which are
+implemented in the GLPK package.} is intended for coding LP/MIP problem
+data. It is a row-oriented format that assumes the formulation of
+LP/MIP problem (1.1)---(1.3) (see Section \ref{seclp}, page
+\pageref{seclp}).
+
+CPLEX LP file is a plain text file written in CPLEX LP format. Each
+text line of this file may contain up to 255 characters\footnote{GLPK
+allows text lines of arbitrary length.}. Blank lines are ignored.
+If a line contains the backslash character ($\backslash$), this
+character and everything that follows it until the end of line are
+considered as a comment and also ignored.
+
+An LP file is coded by the user using the following elements: keywords,
+symbolic names, numeric constants, delimiters, and blanks.
+
+{\it Keywords} which may be used in the LP file are the following:
+
+\begin{verbatim}
+      minimize        minimum        min
+      maximize        maximum        max
+      subject to      such that      s.t.      st.      st
+      bounds          bound
+      general         generals       gen
+      integer         integers       int
+      binary          binaries       bin
+      infinity        inf
+      free
+      end
+\end{verbatim}
+
+\noindent
+All the keywords are case insensitive. Keywords given above on the same
+line are equivalent. Any keyword (except \verb|infinity|, \verb|inf|,
+and \verb|free|) being used in the LP file must start at the beginning
+of a text line.
+
+\newpage
+
+{\it Symbolic names} are used to identify the objective function,
+constraints (rows), and variables (columns). All symbolic names are case
+sensitive and may contain up to 16 alphanumeric characters\footnote{GLPK
+allows symbolic names having up to 255 characters.} (\verb|a|, \dots,
+\verb|z|, \verb|A|, \dots, \verb|Z|, \verb|0|, \dots, \verb|9|) as well
+as the following characters:
+
+\begin{verbatim}
+      !  "  #  $  %  &  (  )  /  ,  .  ;  ?  @  _  `  '  {  }  |  ~
+\end{verbatim}
+
+\noindent
+with exception that no symbolic name can begin with a digit or
+a period.
+
+{\it Numeric constants} are used to denote constraint and objective
+coefficients, right-hand sides of constraints, and bounds of variables.
+They are coded in the standard form $xx$\verb|E|$syy$, where $xx$ is
+a real number with optional decimal point, $s$ is a sign (\verb|+| or
+\verb|-|), $yy$ is an integer decimal exponent. Numeric constants may
+contain arbitrary number of characters. The exponent part is optional.
+The letter `\verb|E|' can be coded as `\verb|e|'. If the sign $s$ is
+omitted, plus is assumed.
+
+{\it Delimiters} that may be used in the LP file are the following:
+
+\begin{verbatim}
+      :
+      +
+      -
+      <   <=   =<
+      >   >=   =>
+      =
+\end{verbatim}
+
+\noindent
+Delimiters given above on the same line are equivalent. The meaning of
+the delimiters will be explained below.
+
+{\it Blanks} are non-significant characters. They may be used freely to
+improve readability of the LP file. Besides, blanks should be used to
+separate elements from each other if there is no other way to do that
+(for example, to separate a keyword from a following symbolic name).
+
+The order of an LP file is:
+
+\vspace*{-8pt}
+
+\begin{itemize}
+\item objective function definition;
+
+\item constraints section;
+
+\item bounds section;
+
+\item general, integer, and binary sections (can appear in arbitrary
+order);
+
+\item end keyword.
+\end{itemize}
+
+\vspace*{-8pt}
+
+These components are discussed in following sections.
+
+\section{Objective function definition}
+
+The objective function definition must appear first in the LP file.
+It defines the objective function and specifies the optimization
+direction.
+
+The objective function definition has the following form:
+$$
+\left\{
+\begin{array}{@{}c@{}}
+{\tt minimize} \\ {\tt maximize}
+\end{array}
+\right\}\ f\ {\tt :}\ s\ c\ x\ s\ c\ x\ \dots\ s\ c\ x
+$$
+where $f$ is a symbolic name of the objective function, $s$ is a sign
+\verb|+| or \verb|-|, $c$ is a numeric constant that denotes an
+objective coefficient, $x$ is a symbolic name of a variable.
+
+If necessary, the objective function definition can be continued on as
+many text lines as desired.
+
+The name of the objective function is optional and may be omitted
+(together with the semicolon that follows it). In this case the default
+name `\verb|obj|' is assigned to the objective function.
+
+If the very first sign $s$ is omitted, the sign plus is assumed. Other
+signs cannot be omitted.
+
+If some objective coefficient $c$ is omitted, 1 is assumed.
+
+Symbolic names $x$ used to denote variables are recognized by context
+and therefore needn't to be declared somewhere else.
+
+Here is an example of the objective function definition:
+
+\begin{verbatim}
+   Minimize Z : - x1 + 2 x2 - 3.5 x3 + 4.997e3x(4) + x5 + x6 +
+      x7 - .01x8
+\end{verbatim}
+
+\section{Constraints section}
+
+The constraints section must follow the objective function definition.
+It defines a system of equality and/or inequality constraints.
+
+The constraint section has the following form:
+
+\begin{center}
+\begin{tabular}{l}
+\verb|subject to| \\
+{\it constraint}$_1$ \\
+{\it constraint}$_2$ \\
+\hspace{20pt}\dots \\
+{\it constraint}$_m$ \\
+\end{tabular}
+\end{center}
+
+\noindent where {\it constraint}$_i, i=1,\dots,m,$ is a particular
+constraint definition.
+
+Each constraint definition can be continued on as many text lines as
+desired. However, each constraint definition must begin on a new line
+except the very first constraint definition which can begin on the same
+line as the keyword `\verb|subject to|'.
+
+Constraint definitions have the following form:
+$$
+r\ {\tt:}\ s\ c\ x\ s\ c\ x\ \dots\ s\ c\ x
+\ \left\{
+\begin{array}{@{}c@{}}
+\mbox{\tt<=} \\ \mbox{\tt>=} \\ \mbox{\tt=}
+\end{array}
+\right\}\ b
+$$
+where $r$ is a symbolic name of a constraint, $s$ is a sign \verb|+| or
+\verb|-|, $c$ is a numeric constant that denotes a constraint
+coefficient, $x$ is a symbolic name of a variable, $b$ is a right-hand
+side.
+
+The name $r$ of a constraint (which is the name of the corresponding
+auxiliary variable) is optional and may be omitted (together with the
+semicolon that follows it). In this case the default names like
+`\verb|r.nnn|' are assigned to unnamed constraints.
+
+The linear form $s\ c\ x\ s\ c\ x\ \dots\ s\ c\ x$ in the left-hand
+side of a constraint definition has exactly the same meaning as in the
+case of the objective function definition (see above).
+
+After the linear form one of the following delimiters that indicates
+the constraint sense must be specified:
+
+\verb|<=| \ means `less than or equal to'
+
+\verb|>=| \ means `greater than or equal to'
+
+\verb|= | \ means `equal to'
+
+The right hand side $b$ is a numeric constant with an optional sign.
+
+Here is an example of the constraints section:
+
+\begin{verbatim}
+   Subject To
+      one: y1 + 3 a1 - a2 - b >= 1.5
+      y2 + 2 a3 + 2
+         a4 - b >= -1.5
+      two : y4 + 3 a1 + 4 a5 - b <= +1
+      .20y5 + 5 a2 - b = 0
+      1.7 y6 - a6 + 5 a777 - b >= 1
+\end{verbatim}
+
+Should note that it is impossible to express ranged constraints in the
+CPLEX LP format. Each a ranged constraint can be coded as two
+constraints with identical linear forms in the left-hand side, one of
+which specifies a lower bound and other does an upper one of the
+original ranged constraint. Another way is to introduce a slack
+double-bounded variable; for example, the
+constraint
+$$10\leq x+2y+3z\leq 50$$
+can be written as follows:
+$$x+2y+3z+t=50,$$
+where $0\leq t\leq 40$ is a slack variable.
+
+\section{Bounds section}
+
+The bounds section is intended to define bounds of variables. This
+section is optional; if it is specified, it must follow the constraints
+section. If the bound section is omitted, all variables are assumed to
+be non-negative (i.e. that they have zero lower bound and no upper
+bound).
+
+The bounds section has the following form:
+
+\begin{center}
+\begin{tabular}{l}
+\verb|bounds| \\
+{\it definition}$_1$ \\
+{\it definition}$_2$ \\
+\hspace{20pt}\dots \\
+{\it definition}$_p$ \\
+\end{tabular}
+\end{center}
+
+\noindent
+where {\it definition}$_k, k=1,\dots,p,$ is a particular bound
+definition.
+
+Each bound definition must begin on a new line\footnote{The GLPK
+implementation allows several bound definitions to be placed on the
+same line.} except the very first bound definition which can begin on
+the same line as the keyword `\verb|bounds|'.
+
+\newpage
+
+Syntactically constraint definitions can have one of the following six
+forms:
+
+\begin{center}
+\begin{tabular}{ll}
+$x$ \verb|>=| $l$ &              specifies a lower bound \\
+$l$ \verb|<=| $x$ &              specifies a lower bound \\
+$x$ \verb|<=| $u$ &              specifies an upper bound \\
+$l$ \verb|<=| $x$ \verb|<=| $u$ &specifies both lower and upper bounds\\
+$x$ \verb|=| $t$                &specifies a fixed value \\
+$x$ \verb|free|                 &specifies free variable
+\end{tabular}
+\end{center}
+
+\noindent
+where $x$ is a symbolic name of a variable, $l$ is a numeric constant
+with an optional sign that defines a lower bound of the variable or
+\verb|-inf| that means that the variable has no lower bound, $u$ is a
+numeric constant with an optional sign that defines an upper bound of
+the variable or \verb|+inf| that means that the variable has no upper
+bound, $t$ is a numeric constant with an optional sign that defines a
+fixed value of the variable.
+
+By default all variables are non-negative, i.e. have zero lower bound
+and no upper bound. Therefore definitions of these default bounds can
+be omitted in the bounds section.
+
+Here is an example of the bounds section:
+
+\begin{verbatim}
+   Bounds
+      -inf <= a1 <= 100
+      -100 <= a2
+      b <= 100
+      x2 = +123.456
+      x3 free
+\end{verbatim}
+
+\section{General, integer, and binary sections}
+
+The general, integer, and binary sections are intended to define
+some variables as integer or binary. All these sections are optional
+and needed only in case of MIP problems. If they are specified, they
+must follow the bounds section or, if the latter is omitted, the
+constraints section.
+
+All the general, integer, and binary sections have the same form as
+follows:
+
+\begin{center}
+\begin{tabular}{l}
+$
+\left\{
+\begin{array}{@{}l@{}}
+\verb|general| \\
+\verb|integer| \\
+\verb|binary | \\
+\end{array}
+\right\}
+$ \\
+\hspace{10pt}$x_1$ \\
+\hspace{10pt}$x_2$ \\
+\hspace{10pt}\dots \\
+\hspace{10pt}$x_q$ \\
+\end{tabular}
+\end{center}
+
+\noindent
+where $x_k$ is a symbolic name of variable, $k=1,\dots,q$.
+
+Each symbolic name must begin on a new line\footnote{The GLPK
+implementation allows several symbolic names to be placed on the same
+line.} except the very first symbolic name which can begin on the same
+line as the keyword `\verb|general|', `\verb|integer|', or
+`\verb|binary|'.
+
+\newpage
+
+If a variable appears in the general or the integer section, it is
+assumed to be general integer variable. If a variable appears in the
+binary section, it is assumed to be binary variable, i.e. an integer
+variable whose lower bound is zero and upper bound is one. (Note that
+if bounds of a variable are specified in the bounds section and then
+the variable appears in the binary section, its previously specified
+bounds are ignored.)
+
+Here is an example of the integer section:
+
+\begin{verbatim}
+   Integer
+      z12
+      z22
+      z35
+\end{verbatim}
+
+\section{End keyword}
+
+The keyword `\verb|end|' is intended to end the LP file. It must begin
+on a separate line and no other elements (except comments and blank
+lines) must follow it. Although this keyword is optional, it is strongly
+recommended to include it in the LP file.
+
+\section{Example of CPLEX LP file}
+
+Here is a complete example of CPLEX LP file that corresponds to the
+example given in Section \ref{secmpsex}, page \pageref{secmpsex}.

+\section*{Preamble}
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+\section*{TERMS AND CONDITIONS}
+
+\subsubsection*{0. Definitions.}
+
+  ``This License'' refers to version 3 of the GNU General Public
+License.
+
+  ``Copyright'' also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+  ``The Program'' refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as ``you''.  ``Licensees'' and
+``recipients'' may be individuals or organizations.
+
+  To ``modify'' a work means to copy from or adapt all or part of the
+work in a fashion requiring copyright permission, other than the making
+of an exact copy.  The resulting work is called a ``modified version''
+of the earlier work or a work ``based on'' the earlier work.
+
+  A ``covered work'' means either the unmodified Program or a work based
+on the Program.
+
+  To ``propagate'' a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To ``convey'' a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays ``Appropriate Legal Notices''
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+\subsubsection*{1. Source Code.}
+
+  The ``source code'' for a work means the preferred form of the work
+for making modifications to it.  ``Object code'' means any non-source
+form of a work.
+
+  A ``Standard Interface'' means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The ``System Libraries'' of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+``Major Component'', in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The ``Corresponding Source'' for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+\subsubsection*{2. Basic Permissions.}
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+\subsubsection*{3. Protecting Users' Legal Rights From
+Anti-Circumvention Law.}
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+\subsubsection*{4. Conveying Verbatim Copies.}
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+\subsubsection*{5. Conveying Modified Source Versions.}
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    ``keep intact all notices''.
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+``aggregate'' if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+\subsubsection*{6. Conveying Non-Source Forms.}
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A ``User Product'' is either (1) a ``consumer product'', which means
+any tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling.  In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of coverage.
+For a particular product received by a particular user, ``normally
+used'' refers to a typical or common use of that class of product,
+regardless of the status of the particular user or of the way in which
+the particular user actually uses, or expects or is expected to use, the
+product.  A product is a consumer product regardless of whether the
+product has substantial commercial, industrial or non-consumer uses,
+unless such uses represent the only significant mode of use of the
+product.
+
+  ``Installation Information'' for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product
+from a modified version of its Corresponding Source.  The information
+must suffice to ensure that the continued functioning of the modified
+object code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to
+a network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+\subsubsection*{7. Additional Terms.}
+
+  ``Additional permissions'' are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered ``further
+restrictions'' within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+\subsubsection*{8. Termination.}
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+\subsubsection*{9. Acceptance Not Required for Having Copies.}
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+\subsubsection*{10. Automatic Licensing of Downstream Recipients.}
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An ``entity transaction'' is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+\subsubsection*{11. Patents.}
+
+  A ``contributor'' is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's ``contributor version''.
+
+  A contributor's ``essential patent claims'' are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, ``control'' includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a ``patent license'' is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To ``grant'' such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  ``Knowingly relying'' means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is ``discriminatory'' if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+\subsubsection*{12. No Surrender of Others' Freedom.}
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not convey it at all.  For example, if you agree to terms that
+obligate you to collect a royalty for further conveying from those to
+whom you convey the Program, the only way you could satisfy both those
+terms and this License would be to refrain entirely from conveying the
+Program.
+
+\subsubsection*{13. Use with the GNU Affero General Public License.}
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+\subsubsection*{14. Revised Versions of this License.}
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License ``or any later version'' applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+\subsubsection*{15. Disclaimer of Warranty.}
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
+PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
+OF THE PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU
+ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+\subsubsection*{16. Limitation of Liability.}
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
+SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
+WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+\subsubsection*{17. Interpretation of Sections 15 and 16.}
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.

+\section*{How to Apply These Terms to Your New Programs}
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+\begin{verbatim}
+   <one line to give the program's name and a brief idea of what it does.>
+   Copyright (C) <year>  <name of author>
+
+   This program is free software: you can redistribute it and/or modify
+   it under the terms of the GNU General Public License as published by
+   the Free Software Foundation, either version 3 of the License, or
+   (at your option) any later version.
+
+   This program is distributed in the hope that it will be useful,
+   but WITHOUT ANY WARRANTY; without even the implied warranty of
+   MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+   GNU General Public License for more details.
+
+   You should have received a copy of the GNU General Public License
+   along with this program.  If not, see <http://www.gnu.org/licenses/>.
+\end{verbatim}
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+\begin{verbatim}
+   <program>  Copyright (C) <year>  <name of author>
+   This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+   This is free software, and you are welcome to redistribute it
+   under certain conditions; type `show c' for details.
+\end{verbatim}
+
+\noindent
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License.  Of course, your
+program's commands might be different; for a GUI interface, you would
+use an ``about box''.
+
+  You should also get your employer (if you work as a programmer) or
+school, if any, to sign a ``copyright disclaimer'' for the program, if
+necessary. For more information on this, and how to apply and follow the
+GNU GPL, see \verb|<http://www.gnu.org/licenses/>|.
+
+  The GNU General Public License does not permit incorporating your
+program into proprietary programs.  If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library.  If this is what you want to do, use the
+GNU Lesser General Public License instead of this License.  But first,
+please read \verb|<http://www.gnu.org/philosophy/why-not-lgpl.html>|.

+cplex.h.
+
+NOTE that this module is NOT a clean room implementation of the CPLEX
+callable library. It only implements a CPLEX-like interface to the GLPK
+API routines, and its main purpose is to provide possibility to build
+and run applications which normally use the CPLEX callable library.
+
+This module approximately corresponds to CPLEX 9.0.
+
+Currently this module can be used as a linear programming solver for
+Concorde, the state-of-the-art computer code for solving the symmetric
+traveling salesman problem (TSP) developed by David Applegate, Robert
+Bixby, Vasek Chvatal, and William Cook. For details about Concorde see
+its web page at http://www.tsp.gatech.edu/concorde.html.
+
+To build Concorde along with GLPK you need to do the following:
+
+1. Configure, build, and install GLPK.
+
+2. Download the Concorde tarball co031219.tgz (version Dec 19, 2003),
+   unpack and unarchive it.
+
+3. Copy files cplex.h and cplex.c to subdirectory concorde/LP/.
+
+4. Create file named lpglpk.c in subdirectory concorde/LP/. This file
+   must contain the following two lines:
+
+      #include "cplex.c"
+      #include "lpcplex8.c"
+
+5. Configure Concorde in usual way (./configure) and then build it with
+   the following command:
+
+      make CPPFLAGS=-I. LPSOLVER_INTERFACE=lpglpk.c LPSOLVER_LIB=-lglpk
+
+   The Concorde executable can be found in subdirectory concorde/TSP/.
+
+Please note that currently this GLPK interface module does not support
+some important features (namely, CPXgetijdiv, CPXmdleave, CPXpivotin,
+CPXpivotout, and CPXstrongbranch), so large (more than 1000 nodes) TSP
+instances cannot be solved in a reasonable time, and some instances may
+cause abnormal termination of Concorde (if CPXgetijdiv is called).

+#  Model I Forest Estate Modelling using GLPK/MathProg
+#  Reading and writing dbf files

+
+#  Forest Management 4th Edition

+
+#  Model I Formulation
+
+/*  Note: This is not the full LP model mentioned in the book.
+Some of the constraints are deliberately omitted in this model for the purpose of clarity.
+
+The features of MathProg in this example are:
+* reading and writing dbf from regular dbf files,
+* reading dbf file (database of shapefile (stands.shp)) (e.g. area parameter),
+* using the area data in the constraints and
+* writing dbf file from result of LP model.
+
+Model I - Harvest Scheduling formulation for Sustainable Forest Management (SFM)
+
+Features are:
+* Net Present Value for the objective function (Revenue - Cost)
+* Harvest Constraints by period - Sustainable Yield per Period
+* Even-Flow Constraint / Volume - Harvest Flow Constraint -  Alpha (1-Apha)
+* Even-Flow Constraint / Volume - Harvest Flow Constraint - Beta  (1 +Beta)
+* Forest / Land Constraint -- Total Area of the forest
+* Forest Stand Constraint  -- Individual stands
+
+What is next? -- Forest Mgt Carbon Accounting for Climate Change
+
+Note: The model file that the data containing in
+the dbf files is public domain material (so it is compatible with the
+GNU GPL) and data can be found in 
+http://warnell.forestry.uga.edu/Warnell/Bettinger/mgtbook/index.htm

+/* Data Envelopment Analysis (DEA)
+ *
+ * DEA quantifies the relative efficiency of decision making units (DMUs) by
+ * finding the efficient frontier in multiple input multiple output data.  The
+ * inputs are resources (eg. number of employees, available machines, ...),
+ * the outputs are productive outputs (eg. contracts made, total sales, ...).
+ * The method is non-parametric.  More details are available in the paper
+ * below.
+ *
+ * Models according to: Seiford, Threall, "Recent developments in DEA", 1990.
+ *
+ * Implementation: Sebastian Nowozin <nowozin@gmail.com>

+   disjoint sets V1 and V2, which maximizes the sum of edge weights
+   w(e), where edge e has one endpoint in V1 and other endpoint in V2.
+
+   Reference:
+   Garey, M.R., and Johnson, D.S. (1979), Computers and Intractability:
+   A guide to the theory of NP-completeness [Network design, Cuts and
+   Connectivity, Maximum Cut, ND16]. */

+/* set of nodes */
+
+var x{i in V}, binary;
+/* x[i] = 0 means that node i is in set V1
+   x[i] = 1 means that node i is in set V2 */
+
+/* We need to include in the objective function only that edges (i,j)
+   from E, for which x[i] != x[j]. This can be modeled through binary
+   variables s[i,j] as follows:
+
+      s[i,j] = x[i] xor x[j] = (x[i] + x[j]) mod 2,                  (1)
+
+   where s[i,j] = 1 iff x[i] != x[j], that leads to the following
+   objective function:
+
+      z = sum{(i,j) in E} w[i,j] * s[i,j].                           (2)
+
+   To describe "exclusive or" (1) we could think that s[i,j] is a minor
+   bit of the sum x[i] + x[j]. Then introducing binary variables t[i,j],
+   which represent a major bit of the sum x[i] + x[j], we can write:
+
+      x[i] + x[j] = s[i,j] + 2 * t[i,j].                             (3)
+
+   An easy check shows that conditions (1) and (3) are equivalent.
+
+   Note that condition (3) can be simplified by eliminating variables
+   s[i,j]. Indeed, from (3) it follows that:
+
+      s[i,j] = x[i] + x[j] - 2 * t[i,j].                             (4)
+
+   Since the expression in the right-hand side of (4) is integral, this
+   condition can be rewritten in the equivalent form:
+
+      0 <= x[i] + x[j] - 2 * t[i,j] <= 1.                            (5)
+
+   (One might note that (5) means t[i,j] = x[i] and x[j].)
+
+   Substituting s[i,j] from (4) to (2) leads to the following objective
+   function:
+
+      z = sum{(i,j) in E} w[i,j] * (x[i] + x[j] - 2 * t[i,j]),       (6)
+
+   which does not include variables s[i,j]. */
