+## Thread safety
+
+Sparsepp follows the trade safety rules of the Standard C++ library. In Particular:
+
+- A single sparsepp hash table is thread safe for reading from multiple threads. For example, given a hash table A, it is safe to read A from thread 1 and from thread 2 simultaneously.
+- If a single hash table is being written to by one thread, then all reads and writes to that hash table on the same or other threads must be protected. For example, given a hash table A, if thread 1 is writing to A, then thread 2 must be prevented from reading from or writing to A.
+- It is safe to read and write to one instance of a type even if another thread is reading or writing to a different instance of the same type. For example, given hash tables A and B of the same type, it is safe if A is being written in thread 1 and B is being read in thread 2.

-// they are pointers, unlike typical use), or else a pointer to
-// something that supports a Read()/Write() method.
-//
-// For technical reasons, we implement read_data/write_data in two
-// stages. The actual work is done in *_data_internal, which takes
-// the stream argument twice: once as a template type, and once with
-// normal type information. (We only use the second version.) We do
-// this because of how C++ picks what function overload to use. If we
-// implemented this the naive way:
-// bool read_data(istream* is, const void* data, size_t length);
-// template<typename T> read_data(T* fp, const void* data, size_t length);
-// C++ would prefer the second version for every stream type except
-// istream. However, we want C++ to prefer the first version for
-// streams that are *subclasses* of istream, such as istringstream.
-// This is not possible given the way template types are resolved. So
-// we split the stream argument in two, one of which is templated and
-// one of which is not. The specialized functions (like the istream
-// version above) ignore the template arg and use the second, 'type'
-// arg, getting subclass matching as normal. The 'catch-all'
-// functions (the second version above) use the template arg to deduce
-// the type, and use a second, void* arg to achieve the desired
-// 'catch-all' semantics.

-// A sparsetable is a random container that implements a sparse array,
-// that is, an array that uses very little memory to store unassigned
-// indices (in this case, between 1-2 bits per unassigned index). For
-// instance, if you allocate an array of size 5 and assign a[2] = <big
-// struct>, then a[2] will take up a lot of memory but a[0], a[1],
-// a[3], and a[4] will not. Array elements that have a value are
-// called "assigned". Array elements that have no value yet, or have
-// had their value cleared using erase() or clear(), are called
-// "unassigned".
-//
-// Unassigned values seem to have the default value of T (see below).
-// Nevertheless, there is a difference between an unassigned index and
-// one explicitly assigned the value of T(). The latter is considered
-// assigned.
-//
-// Access to an array element is constant time, as is insertion and
-// deletion. Insertion and deletion may be fairly slow, however:
-// because of this container's memory economy, each insert and delete
-// causes a memory reallocation.
-//
-// NOTE: You should not test(), get(), or set() any index that is
-// greater than sparsetable.size(). If you need to do that, call
-// resize() first.
-//
-// --- Template parameters
-// PARAMETER DESCRIPTION DEFAULT
-// T The value of the array: the type of --
-// object that is stored in the array.
-//
-// Alloc: Allocator to use to allocate memory. libc_allocator_with_realloc
-//
-// --- Model of
-// Random Access Container
-//
-// --- Type requirements
-// T must be Copy Constructible. It need not be Assignable.

-//
-// [*] All iterators are const in a sparsetable (though nonempty_iterators
-// may not be). Use get() and set() to assign values, not iterators.
-//
-// [+] iterators are random-access iterators. nonempty_iterators are
-// bidirectional iterators.
-
-// [*] If you shrink a sparsetable using resize(), assigned elements
-// past the end of the table are removed using erase(). If you grow
-// a sparsetable, new unassigned indices are created.
-//
-// [+] Note that operator[] returns a const reference. You must use
-// set() to change the value of a table element.
-//
-// [!] Unassignment also calls the destructor.
-//
-// Iterators are invalidated whenever an item is inserted or
-// deleted (ie set() or erase() is used) or when the size of
-// the table changes (ie resize() or clear() is used).

-// much machinery STL requires to do even the most trivial tasks.
-//
-// A NOTE ON ASSIGNING:
-// A sparse table does not actually allocate memory for entries
-// that are not filled. Because of this, it becomes complicated
-// to have a non-const iterator: we don't know, if the iterator points
-// to a not-filled bucket, whether you plan to fill it with something
-// or whether you plan to read its value (in which case you'll get
-// the default bucket value). Therefore, while we can define const
-// operations in a pretty 'normal' way, for non-const operations, we
-// define something that returns a helper object with operator= and
-// operator& that allocate a bucket lazily. We use this for table[]
-// and also for regular table iterators.

-// into t/M *groups* of M buckets each. (M is a constant, typically
-// 32) Each group is stored sparsely.
-// Thus, inserting into the table causes some array to grow, which is
-// slow but still constant time. Lookup involves doing a
-// logical-position-to-sparse-position lookup, which is also slow but
-// constant time. The larger M is, the slower these operations are
-// but the less overhead (slightly).
-//
-// To store the sparse array, we store a bitmap B, where B[i] = 1 iff
-// bucket i is non-empty. Then to look up bucket i we really look up
-// array[# of 1s before i in B]. This is constant time for fixed M.
-//
-// Terminology: the position of an item in the overall table (from
-// 1 .. t) is called its "location." The logical position in a group
-// (from 1 .. M) is called its "position." The actual location in
-// the array (from 1 .. # of non-empty buckets in the group) is
-// called its "offset."

- Since items are not grouped into buckets, Bucket APIs have been adapted: `max_bucket_count` is equivalent to `max_size`, and `bucket_count` returns the sparsetable size, which is normally at least twice the number of items inserted into the hash_map.
+## Memory allocator on Windows (when building with Visual Studio)
+
+When building with the Microsoft compiler, we provide a custom allocator because the default one (from the Visual C++ runtime) fragments memory when reallocating.
+
+This is desirable *only* when creating large sparsepp hash maps. If you create lots of small hash_maps, memory usage may increase instead of decreasing as expected. The reason is that, for each instance of a hash_map, the custom memory allocator creates a new memory space to allocate from, which is typically 4K, so it may be a big waste if just a few items are allocated.
+
+In order to use the custom spp allocator, define the following preprocessor variable before including `<spp/spp.h>`:
+
+`#define SPP_USE_SPP_ALLOC 1`
+
## Integer keys, and other hash function considerations.
1. For basic integer types, sparsepp provides a default hash function which does some mixing of the bits of the keys (see [Integer Hashing](http://burtleburtle.net/bob/hash/integer.html)). This prevents a pathological case where inserted keys are sequential (1, 2, 3, 4, ...), and the lookup on non-present keys becomes very slow.

+// Adaptor methods for reading/writing data from an INPUT or OUPTUT
+// variable passed to serialize() or unserialize(). For now we
+// have implemented INPUT/OUTPUT for FILE*, istream*/ostream* (note
+// they are pointers, unlike typical use), or else a pointer to
+// something that supports a Read()/Write() method.
+//
+// For technical reasons, we implement read_data/write_data in two
+// stages. The actual work is done in *_data_internal, which takes
+// the stream argument twice: once as a template type, and once with
+// normal type information. (We only use the second version.) We do
+// this because of how C++ picks what function overload to use. If we
+// implemented this the naive way:
+// bool read_data(istream* is, const void* data, size_t length);
+// template<typename T> read_data(T* fp, const void* data, size_t length);
+// C++ would prefer the second version for every stream type except
+// istream. However, we want C++ to prefer the first version for
+// streams that are *subclasses* of istream, such as istringstream.
+// This is not possible given the way template types are resolved. So
+// we split the stream argument in two, one of which is templated and
+// one of which is not. The specialized functions (like the istream
+// version above) ignore the template arg and use the second, 'type'
+// arg, getting subclass matching as normal. The 'catch-all'
+// functions (the second version above) use the template arg to deduce
+// the type, and use a second, void* arg to achieve the desired
+// 'catch-all' semantics.

+// A sparsetable is a random container that implements a sparse array,
+// that is, an array that uses very little memory to store unassigned
+// indices (in this case, between 1-2 bits per unassigned index). For
+// instance, if you allocate an array of size 5 and assign a[2] = <big
+// struct>, then a[2] will take up a lot of memory but a[0], a[1],
+// a[3], and a[4] will not. Array elements that have a value are
+// called "assigned". Array elements that have no value yet, or have
+// had their value cleared using erase() or clear(), are called
+// "unassigned".
+//
+// Unassigned values seem to have the default value of T (see below).
+// Nevertheless, there is a difference between an unassigned index and
+// one explicitly assigned the value of T(). The latter is considered
+// assigned.
+//
+// Access to an array element is constant time, as is insertion and
+// deletion. Insertion and deletion may be fairly slow, however:
+// because of this container's memory economy, each insert and delete
+// causes a memory reallocation.
+//
+// NOTE: You should not test(), get(), or set() any index that is
+// greater than sparsetable.size(). If you need to do that, call
+// resize() first.
+//
+// --- Template parameters
+// PARAMETER DESCRIPTION DEFAULT
+// T The value of the array: the type of --
+// object that is stored in the array.
+//
+// Alloc: Allocator to use to allocate memory.
+//
+// --- Model of
+// Random Access Container
+//
+// --- Type requirements
+// T must be Copy Constructible. It need not be Assignable.
+//
+// --- Public base classes
+// None.
+//
+// --- Members
+//
+// [*] All iterators are const in a sparsetable (though nonempty_iterators
+// may not be). Use get() and set() to assign values, not iterators.
+//
+// [+] iterators are random-access iterators. nonempty_iterators are
+// bidirectional iterators.
+
+// [*] If you shrink a sparsetable using resize(), assigned elements
+// past the end of the table are removed using erase(). If you grow
+// a sparsetable, new unassigned indices are created.
+//
+// [+] Note that operator[] returns a const reference. You must use
+// set() to change the value of a table element.
+//
+// [!] Unassignment also calls the destructor.
+//
+// Iterators are invalidated whenever an item is inserted or
+// deleted (ie set() or erase() is used) or when the size of
+// the table changes (ie resize() or clear() is used).
+
+
+
+// ---------------------------------------------------------------------------
+// Our iterator as simple as iterators can be: basically it's just
+// the index into our table. Dereference, the only complicated
+// thing, we punt to the table class. This just goes to show how
+// much machinery STL requires to do even the most trivial tasks.
+//
+// A NOTE ON ASSIGNING:
+// A sparse table does not actually allocate memory for entries
+// that are not filled. Because of this, it becomes complicated
+// to have a non-const iterator: we don't know, if the iterator points
+// to a not-filled bucket, whether you plan to fill it with something
+// or whether you plan to read its value (in which case you'll get
+// the default bucket value). Therefore, while we can define const
+// operations in a pretty 'normal' way, for non-const operations, we
+// define something that returns a helper object with operator= and
+// operator& that allocate a bucket lazily. We use this for table[]
+// and also for regular table iterators.

+//
+// By templatizing over tabletype, we have one iterator type which
+// we can use for both sparsetables and sparsebins. In fact it
+// works on any class that allows size() and operator[] (eg vector),
+// as long as it does the standard STL typedefs too (eg value_type).

+// SPARSE-TABLE
+// ------------
+// The idea is that a table with (logically) t buckets is divided
+// into t/M *groups* of M buckets each. (M is a constant, typically
+// 32) Each group is stored sparsely.
+// Thus, inserting into the table causes some array to grow, which is
+// slow but still constant time. Lookup involves doing a
+// logical-position-to-sparse-position lookup, which is also slow but
+// constant time. The larger M is, the slower these operations are
+// but the less overhead (slightly).
+//
+// To store the sparse array, we store a bitmap B, where B[i] = 1 iff
+// bucket i is non-empty. Then to look up bucket i we really look up
+// array[# of 1s before i in B]. This is constant time for fixed M.
+//
+// Terminology: the position of an item in the overall table (from
+// 1 .. t) is called its "location." The logical position in a group
+// (from 1 .. M) is called its "position." The actual location in
+// the array (from 1 .. # of non-empty buckets in the group) is
+// called its "offset."

+
+ Each tree holding treenodes is a tree of unique chunk sizes. Chunks
+ of the same size are arranged in a circularly-linked list, with only
+ the oldest chunk (the next to be used, in our FIFO ordering)
+ actually in the tree. (Tree members are distinguished by a non-null
+ parent pointer.) If a chunk with the same size an an existing node
+ is inserted, it is linked off the existing node using pointers that
+ work in the same way as fd/bk pointers of small chunks.
+
+ Each tree contains a power of 2 sized range of chunk sizes (the
+ smallest is 0x100 <= x < 0x180), which is is divided in half at each
+ tree level, with the chunks in the smaller half of the range (0x100
+ <= x < 0x140 for the top nose) in the left subtree and the larger
+ half (0x140 <= x < 0x180) in the right subtree. This is, of course,
+ done by inspecting individual bits.
+
+ Using these rules, each node's left subtree contains all smaller
+ sizes than its right subtree. However, the node at the root of each
+ subtree has no particular ordering relationship to either. (The
+ dividing line between the subtree sizes is based on trie relation.)
+ If we remove the last chunk of a given size from the interior of the
+ tree, we need to replace it with a leaf node. The tree ordering
+ rules permit a node to be replaced by any leaf below it.
+
+ The smallest chunk in a tree (a common operation in a best-fit
+ allocator) can be found by walking a path to the leftmost leaf in
+ the tree. Unlike a usual binary tree, where we follow left child
+ pointers until we reach a null, here we follow the right child
+ pointer any time the left one is null, until we reach a leaf with
+ both child pointers null. The smallest chunk in the tree will be
+ somewhere along that path.
+
+ The worst case number of steps to add, find, or remove a node is
+ bounded by the number of bits differentiating chunks within
+ bins. Under current bin calculations, this ranges from 6 up to 21
+ (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+ is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+ Each malloc space may include non-contiguous segments, held in a
+ list headed by an embedded malloc_segment record representing the
+ top-most space. Segments also include flags holding properties of
+ the space. Large chunks that are directly allocated by mmap are not
+ included in this list. They are instead independently created and
+ destroyed without otherwise keeping track of them.
+
+ Segment management mainly comes into play for spaces allocated by
+ MMAP. Any call to MMAP might or might not return memory that is
+ adjacent to an existing segment. MORECORE normally contiguously
+ extends the current space, so this space is almost always adjacent,
+ which is simpler and faster to deal with. (This is why MORECORE is
+ used preferentially to MMAP when both are available -- see
+ sys_alloc.) When allocating using MMAP, we don't use any of the
+ hinting mechanisms (inconsistently) supported in various
+ implementations of unix mmap, or distinguish reserving from
+ committing memory. Instead, we just ask for space, and exploit
+ contiguity when we get it. It is probably possible to do
+ better than this on some systems, but no general scheme seems
+ to be significantly better.
+
+ Management entails a simpler variant of the consolidation scheme
+ used for chunks to reduce fragmentation -- new adjacent memory is
+ normally prepended or appended to an existing segment. However,
+ there are limitations compared to chunk consolidation that mostly
+ reflect the fact that segment processing is relatively infrequent
+ (occurring only when getting memory from system) and that we
+ don't expect to have huge numbers of segments:
+
+ * Segments are not indexed, so traversal requires linear scans. (It
+ would be possible to index these, but is not worth the extra
+ overhead and complexity for most programs on most platforms.)
+ * New segments are only appended to old ones when holding top-most
+ memory; if they cannot be prepended to others, they are held in
+ different segments.
+
+ Except for the top-most segment of an mstate, each segment record
+ is kept at the tail of its segment. Segments are added by pushing
+ segment records onto the list headed by &mstate.seg for the
+ containing mstate.
+
+ Segment flags control allocation/merge/deallocation policies:
+ * If EXTERN_BIT set, then we did not allocate this segment,
+ and so should not try to deallocate or merge with others.
+ (This currently holds only for the initial segment passed
+ into create_mspace_with_base.)
+ * If USE_MMAP_BIT set, the segment may be merged with
+ other surrounding mmapped segments and trimmed/de-allocated
+ using munmap.
+ * If neither bit is set, then the segment was obtained using
+ MORECORE so can be merged with surrounding MORECORE'd segments
+ and deallocated/trimmed using MORECORE with negative arguments.

+ A malloc_state holds all of the bookkeeping for a space.
+ The main fields are:
+
+ Top
+ The topmost chunk of the currently active segment. Its size is
+ cached in topsize. The actual size of topmost space is
+ topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+ fenceposts and segment records if necessary when getting more
+ space from the system. The size at which to autotrim top is
+ cached from mparams in trim_check, except that it is disabled if
+ an autotrim fails.
+
+ Designated victim (dv)
+ This is the preferred chunk for servicing small requests that
+ don't have exact fits. It is normally the chunk split off most
+ recently to service another small request. Its size is cached in
+ dvsize. The link fields of this chunk are not maintained since it
+ is not kept in a bin.
+
+ SmallBins
+ An array of bin headers for free chunks. These bins hold chunks
+ with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+ chunks of all the same size, spaced 8 bytes apart. To simplify
+ use in double-linked lists, each bin header acts as a malloc_chunk
+ pointing to the real first node, if it exists (else pointing to
+ itself). This avoids special-casing for headers. But to avoid
+ waste, we allocate only the fd/bk pointers of bins, and then use
+ repositioning tricks to treat these as the fields of a chunk.
+
+ TreeBins
+ Treebins are pointers to the roots of trees holding a range of
+ sizes. There are 2 equally spaced treebins for each power of two
+ from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+ larger.
+
+ Bin maps
+ There is one bit map for small bins ("smallmap") and one for
+ treebins ("treemap). Each bin sets its bit when non-empty, and
+ clears the bit when empty. Bit operations are then used to avoid
+ bin-by-bin searching -- nearly all "search" is done without ever
+ looking at bins that won't be selected. The bit maps
+ conservatively use 32 bits per map word, even if on 64bit system.
+ For a good description of some of the bit-based techniques used
+ here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+ supplement at http://hackersdelight.org/). Many of these are
+ intended to reduce the branchiness of paths through malloc etc, as
+ well as to reduce the number of memory locations read or written.
+
+ Segments
+ A list of segments headed by an embedded malloc_segment record
+ representing the initial space.
+
+ Address check support
+ The least_addr field is the least address ever obtained from
+ MORECORE or MMAP. Attempted frees and reallocs of any address less
+ than this are trapped (unless SPP_INSECURE is defined).
+
+ Magic tag
+ A cross-check field that should always hold same value as mparams._magic.
+
+ Max allowed footprint
+ The maximum allowed bytes to allocate from system (zero means no limit)
+
+ Flags
+ Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+ Statistics
+ Each space keeps track of current and maximum system memory
+ obtained via MORECORE or MMAP.
+
+ Trim support
+ Fields holding the amount of unused topmost memory that should trigger
+ trimming, and a counter to force periodic scanning to release unused
+ non-topmost segments.
+
+ Extension support
+ A void* pointer and a size_t field that can be used to help implement
+ extensions to this malloc.

+ computed by any code successfully malloc'ing any chunk, so does not
+ itself provide protection against code that has already broken

All notable changes to Sylvan will be documented in this file.
## [Unreleased]
+### Changed
+- We now implement twisted tabulation as the hash function for the nodes table. The old hash function is still available and the default behavior can be changed in `sylvan_table.h`.
+
+## [1.4.0] - 2017-07-12
+### Added
+- Function `mtbdd_cmpl` that computes the complement for MTBDDs. (0 becomes 1, non-0 becomes 0)
+
+### Changed
+- Changed file formats used by the examples to match the changes in LTSmin.
+- Function `mtbdd_satcount` now does not count assignments leading to 0. Perhaps in the future we make this configurable. (Like in CuDD.)
+- Slightly improved C++ support by wrapping header files in the namespace sylvan.
+
+### Fixed
+- There was a bug where Lace tasks are overwritten during SYNC, which causes problems during garbage collection. Lace reusing the bucket during SYNC is by design and is difficult to change. We fix the issue by checking during garbage collection if the stored task is still the same function, which in the worst case marks more nodes than needed.
+- Band-aid patch for hashing; very similar nodes were hashing to similar positions and strides, causing early garbage collections and full tables. The patch works for now, but we need a more robust solution.
+
+### Removed
+- Removed support for HWLOC (pinning on NUMA machines). Planning to bring this back as an option, but in its current form it prevents multiple Sylvan programs from running simultaneously on the same machine.
+
+## [1.3.3] - 2017-06-03
+### Changed
+- Changed file format for .bdd files in the MC example.
+
+### Fixed
+- A major bug in `lddmc_match_sat_par` has been fixed.
+- A bug in the saturation algorithm in the model checking example has been fixed.
+- A major bug in the hash table rehashing implementation has been fixed.
+
+## [1.3.2] - 2017-05-23
+### Added
+- Now implements `lddmc_protect` and `lddmc_unprotect` for external pointer references.
+- Now implements `lddmc_refs_pushptr` and `lddmc_refs_popptr` for internal pointer references
+
+### Changed
+- New version of Lace has slightly different API for manually created threads.
+
+## [1.3.1] - 2017-05-22
+### Fixed
+- A bug in `mtbdd_refs_ptrs_up` caused a segfault. This has been fixed.
+
+## [1.3.0] - 2017-05-16
### Added
- The embedded work-stealing framework now explicitly checks for stack overflows and aborts with an appropriate error message written to stderr.
- New functions `sylvan_project` and `sylvan_and_project` for BDDs, a dual of existential quantification, where instead of the variables to remove, the given set of variables are the variables to keep.
+- New functions `mtbdd_refs_pushptr` and `mtbdd_refs_popptr` allow thread-specific referencing of pointers.
### Changed
- Rewritten initialization of Sylvan. Before the call to `sylvan_init_package`, table sizes must be initialized either using `sylvan_set_sizes` or with the new function `sylvan_set_limits`. This new function allows the user to set a maximum number of bytes allocated for the nodes table and for the operation cache.
+- Rewritten MTBDD referencing system.
+- Rewritten MTBDD map and set functions (no API change except renaming `mtbdd_map_addall` to `mtbdd_map_update` with backward compatibility)
+- The lock-free unique table now uses double hashing instead of rehashing. This can improve the performance for custom leaves and improves the hash spread.
+
+### Fixed
+- A bug in `llmsset_lookup` affecting custom leaves has been fixed.
## [1.2.0] - 2017-02-03

@@ -121,98 +124,207 @@ Like all decision diagram implementations, Sylvan performs garbage collection.
Garbage collection is triggered when trying to insert a new node and no
empty space can be found in the table within a reasonable upper bound.
+Garbage collection can be disabled with ``sylvan_gc_disable`` and enabled again with ``sylvan_gc_enable``.
+Call ``sylvan_gc`` to manually trigger garbage collection.
+
To ensure that no decision diagram nodes are overwritten, you must ensure that
Sylvan knows which decision diagrams you care about.
-The easiest way to do this is with ``sylvan_protect`` and ``sylvan_unprotect`` to protect
-a given pointer.
-These functions protect the decision diagram referenced to by that pointer at the time
-that garbage collection is performed.
-Unlike some other implementations of decision diagrams,
-you can modify the variable between the calls to ``sylvan_protect`` and ``sylvan_unprotect``
-without explicitly changing the reference.
-
-To manually trigger garbage collection, call ``sylvan_gc``.
-You can use ``sylvan_gc_disable`` and ``sylvan_gc_enable`` to disable garbage collection or
-enable it again. If garbage collection is disabled, the program will abort when the nodes table
-is full.
+Each subpackage implements mechanisms to store references to decision diagrams that must be kept.
+For example, the *mtbdd* subpackage implements ``mtbdd_protect`` and ``mtbdd_unprotect`` to store pointers to
+MTBDD variables.
+
+.. code:: c
+
+ MTBDD* allocate_var() {
+ MTBDD* my_var = (MTBDD*)calloc(sizeof(MTBDD), 1);
+ mtbdd_protect(my_var);
+ return my_var;
+ }
+
+ free_var(MTBDD* my_var) {
+ mtbdd_unprotect(my_var);
+ free(my_var);
+ }
+
+If you use ``mtbdd_protect`` you do not need to update the reference every time the value changes.
+
+The *mtbdd* subpackage also implements thread-local stacks to temporarily store pointers and results of tasks:
+
+.. code:: c
+
+ MTBDD some_thing = ...;
+ mtbdd_refs_pushptr(&some_thing);
+ MTBDD result_param1 = mtbdd_false, result_param2 = mtbdd_false;
+ mtbdd_refs_pushptr(&result_param1);
+ mtbdd_refs_pushptr(&result_param2);
+ while (some_condition) {
+ mtbdd_refs_spawn(SPAWN(an_operation, some_thing, param1));
+ result_param2 = CALL(an_operation, some_thing, param2);
+ result_param1 = mtbdd_refs_sync(SYNC(an_operation));
+ some_thing = CALL(another_operation, result1, result2);
+ }
+ mtbdd_refs_popptr(3);
+ return some_thing;
+
+It is recommended to use the thread-local stacks for local variables, and to use the ``protect`` and ``unprotect``
+functions for other variables. Every SPAWN and SYNC of a Lace task that returns an MTBDD must be decorated with
+``mtbdd_refs_stack`` and ``mtbdd_refs_sync`` as in the above example.
+
+References to decision diagrams must be added before a worker may cooperate on garbage collection.
+Workers can cooperate on garbage collection during ``SYNC`` and when functions create nodes or use ``sylvan_gc_test`` to test whether to assist in garbage collection.
+Functions for adding or removing references never perform garbage collection.
+Furthermore, only the ``mtbdd_makenode`` function (and other node making primitives) implicitly reference their parameters; all other functions do not reference their parameters.
+Nesting Sylvan functions (including ``sylvan_ithvar``) is bad practice and should be avoided.
+
**Warning**: Sylvan is a multi-threaded library and all workers must cooperate for garbage collection. If you use locking mechanisms in your code, beware of deadlocks!
+You can explicitly cooperate on garbage collection with ``sylvan_gc_test()``.

+Basic BDD/MTBDD functionality
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Basic BDD functionality
-~~~~~~~~~~~~~~~~~~~~~~~
+In Sylvan, BDDs are special cases of MTBDDs.
+Several functions are specific for BDDs and they start with ``sylvan_``, whereas generic MTBDD functions start
+with ``mtbdd_``.
To create new BDDs, you can use:
-- ``sylvan_true``: representation of constant ``true``.
-- ``sylvan_false``: representation of constant ``false``.

+A number of convencience functions are defined to manipulate sets of variables:
+
+- ``mtbdd_set_empty()``: obtain an empty set.
+- ``mtbdd_set_isempty(set)``: compute whether the set is empty.
+- ``mtbdd_set_first(set)``: obtain the first variable of the set.
+- ``mtbdd_set_next(set)``: obtain the subset without the first variable.
+- ``mtbdd_set_from_array(arr, len)``: create a set from a given array.
+- ``mtbdd_set_to_array(set, arr)``: write the set to the given array.
+- ``mtbdd_set_add(set, var)``: compute the set plus the variable.
+- ``mtbdd_set_union(set1, set2)``: compute the union of two sets.
+- ``mtbdd_set_remove(set, var)``: compute the set minus the variable.
+- ``mtbdd_set_minus(set1, set2)``: compute the set <set1> minus the variables in <set2>.
+- ``mtbdd_set_count(set)``: compute the number of variables in the set.
+- ``mtbdd_set_contains(set, var)``: compute whether the set contains the variable.
+
+Sylvan also implements composition and substitution/variable renaming using a "MTBDD map". An MTBDD map is a special structure
+implemented with special MTBDD nodes to store a mapping from variables (uint32_t) to MTBDDs. Like sets of variables and MTBDDs, MTBDD maps must
+also be referenced for garbage collection. The following functions are related to MTBDD maps:
+
+- ``mtbdd_compose(dd, map)``: apply the map to the given decision diagram, transforming every node with a variable that is associated with some function F in the map by ``if <F> then <high> else <low>``.
+- ``sylvan_compose(dd, map)``: same as ``mtbdd_compose``, but assumes the decision diagram only has Boolean leaves.
+- ``mtbdd_map_empty()``: obtain an empty map.
+- ``mtbdd_map_isempty(map)``: compute whether the map is empty.
+- ``mtbdd_map_key(map)``: obtain the key of the first pair of the map.
+- ``mtbdd_map_value(map)``: obtain the value of the first pair of the map.
+- ``mtbdd_map_next(map)``: obtain the submap without the first pair.
+- ``mtbdd_map_add(map, key, value)``: compute the map plus the given key-value pair.
+- ``mtbdd_map_update(map1, map2)``: compute the union of two maps, with priority to map2 if both maps share variables.
+- ``mtbdd_map_remove(map, var)``: compute the map minus the variable.
+- ``mtbdd_map_removeall(map, set)``: compute the map minus the given variables.
+- ``mtbdd_map_count(set)``: compute the number of pairs in the map.
+- ``mtbdd_map_contains(map, var)``: compute whether the map contains the variable.
+
+Sylvan implements a number of counting operations:
+
+- ``mtbdd_satcount(bdd, number_of_vars)``: compute the number of minterms (assignments that lead to True) for a function with <number_of_vars> variables; we don't need to know the exact variables that may be in the BDD, just how many there are.
+- ``sylvan_pathcount(bdd)``: compute the number of distinct paths to True.
+- ``mtbdd_nodecount(bdd)``: compute the number of nodes (and leaves) in the BDD.
+- ``mtbdd_nodecount_more(array, length)``: compute the number of nodes (and leaves) in the array of BDDs.
+
+Sylvan implements various advanced operations:
+
+- ``sylvan_and_exists(bdd_a, bdd_b, vars)``: compute ``sylvan_exists(sylvan_and(bdd_a, bdd_b), vars)`` in one step.
+- ``sylvan_and_project(bdd_a, bdd_b, vars)``: compute ``sylvan_project(sylvan_and(bdd_a, bdd_b), vars)`` in one step.
+- ``sylvan_cube(vars, values)``: compute a cube (to leaf True) of the given variables, where the array values indicates for each variable whether to use it in negative form (value 0) or positive form (value 1) or to skip it (as dont-care, value 2).
+- ``sylvan_union_cube(set, vars, values)``: compute ``sylvan_or(set, sylvan_cube(vars, values))`` in one step.
+- ``sylvan_constrain(bdd_f, bdd_c)``: compute the generic cofactor of F constrained by C, i.e, set F to False for all assignments not in C.
+- ``sylvan_restrict(bdd_f, bdd_c)``: compute Coudert and Madre's restrict algorithm, which tries to minimize bdd_f according to a care set C using sibling substitution; the invariant is ``restrict(f, c) \and c == f \and c``; the result of this algorithm is often but not always smaller than the original.
+- ``sylvan_pick_cube(bdd)`` or ``sylvan_sat_one_bdd(bdd)``: extract a single path to True from the BDD (returns the BDD of this path)
+- ``sylvan_pick_single_cube(bdd, vars)`` or ``sylvan_sat_single(bdd, vars)`` extracts a single minterm from the BDD (returns the BDD of this assignment)
+- ``sylvan_sat_one(bdd, vars, array)``: extract a single minterm from the BDD given the set of variables and write the values of the variables in order to the given array, with 0 when it is negative, 1 when it is positive, and 2 when it is dontcare.
+
+Sylvan implements several operations for transition systems. These operations assume an interleaved variable ordering, such that *source* or *unprimed* variables have even parity (0, 2, 4...) and matching *target* or *primed* variables have odd parity (1, 3, 5...).
+The transition relations may be partial transition relations that only manipulate a subset of variables; hence, the operations also require the set of variables.
+
+- ``sylvan_relnext(set, relation, vars)``: apply the (partial) relation on the given variables to the set.
+- ``sylvan_relprev(relation, set, vars)``: apply the (partial) relation in reverse to the set; this computes predecessors but can also concatenate relations as follows: ``sylvan_relprev(rel1, rel2, rel1_vars)``.
+- ``sylvan_closure(relation)``: compute the transitive closure of the given set recursively (see Matsunaga et al, DAC 1993)
+
+See ``src/sylvan_bdd.h`` and ``src/mtbdd.h`` for other operations on BDDs and MTBDDs.
+
+Custom leaves
+~~~~~~~~~~~~~
+
+See ``src/sylvan_mt.h`` and the example in ``src/sylvan_gmp.h`` and ``src/sylvan_gmp.c`` for custom leaves in MTBDDs.
+
+Custom decision diagram operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Adding custom decision diagram operations is easy. Include ``sylvan_int.h`` for the internal functions. See ``sylvan_cache.h``
+for how to use the operation cache.
+
+List decision diagrams
+~~~~~~~~~~~~~~~~~~~~~~
+
+See ``src/sylvan_ldd.h`` for operations on list decision diagrams.
+
+File I/O
+~~~~~~~~
+
+You can store and load BDDs using a number of methods, which are documented in the header files ``sylvan_mtbdd.h`` and ``sylvan_ldd.h``.
Support for C++

Table resizing
~~~~~~~~~~~~~~
During garbage collection, it is possible to resize the nodes table and
-the cache. Sylvan provides two default implementations: an aggressive
-version that resizes every time garbage collection is performed, and a
+the cache. By default, Sylvan doubles the table sizes during every garbage
+collection until the maximum table size has been reached. There is also a
less aggressive version that only resizes when at least half the table is
full. This can be configured in ``src/sylvan_config.h``. It is not
possible to decrease the size of the nodes table and the cache.
