Fixed several bugs in several modules (bit vector, parser, etc.). Topological value iteration now works for the consensus protocol and the two dice example.

Added a simple module that handles segfaults: print a message and provide a backtrace.
I grew tired of always starting gdb when it would've sufficed to know the function.
This routine will demangle C++ symbols, so you can see in which function we crashed.

Added native matrix-vector multiplication for our matrix format (as fast as gmm++). Fixed bug in bit vector. Fixed some issues in SCC decomposition. MDP model checkers now have the solving methods by default (native ones) and may override them with their own ones, if desired. Added some aux stuff, like vector helper methods.

Moved model checking of DTMCs to superclass. Now, each DTMC model checker only needs to implement matrix-vector multiplication and linear equation solving to be able to fully model check DTMCs. Added subset/disjoint functionality to bit vector. Changed tests for MDP and DTMC model checking a bit.

Prepared methods for performing reachability searches for non-deterministic models. Removed storage of backward transition relation: it is now (re-)created on demand in the model checkers.

Some minor fixes to GraphAnalyzer and model checkers.

7d95a45633
Fixed bug in AbstractModelChecker: it does now correctly inherit from a lot more interface classes. NOTE: checking a formula on a model checker that does not support it failed silently. This should NOT be the case. Re-enabled DEBUG option for cmake. NOTE: why was this disabled anyway? Introduced another layer AbstractDeterministicModel and AbstractNonDeterministicModel in model hierarchy to allow for easily distinguishing these classes. Made necessary adaptions in (hopefully) all classes. Move the graph analyzer to utility folder.

First test case for prctl parser, and some necessary modifications for
the code
13 years ago
726569d5f1
Fixed bug in parser that inserted 0-entries on the diagonal at the wrong places. Enabled link-time-optimizations for Release-Build when using clang. Fixed bug in base exception: what() returned a pointer to a char array belonging to a local variable, which got deallocated and thus invalidates the char array content.

Added a test to verify the RowSum Function in the Sparse Matrix.
Added an option to the settings for auto-fixing missing no-selfloop states. Kind of a super-option above fix-nodeadlocks, perhaps some Cleanup later on.
Modified tra Files to comply with formats...

Added singleton utility class for CUDD-based things. Added some first methods to expression classes to generate ADDs, but this should be moved to a separate class implementing the expression visitor pattern.

adding sloppy mode for Settings, load settings in tests
sloppy mode will not check for requirements of arguments.
this is somewhat ugly, as it might not even check for correct type (I'm not sure about that, as we only have strings right now), but it's only the tests-binary anyway...

implemented check for deadlocks in parser
Add new option --fix-deadlocks.
Check for deadlocks in nodes.
If option is not set, throw an error if a deadlock is found.

Renaming MRMC to STORM, see #42
Markt und Straßen stehn verlassen,
still erleuchtet jedes Haus,
Sinnend' geh ich durch die Gassen,
alles sieht so festlich aus.
An den Fenstern haben Frauen
buntes Spielzeug fromm geschmückt,
Tausend Kindlein stehn und schauen,
sind so wunderstill beglückt.
Und ich wandre aus den Mauern
Bis hinaus ins freie Feld,
Hehres Glänzen, heil'ges Schauern!
Wie so weit und still die Welt!
Sterne hoch die Kreise schlingen,
Aus des Schnees Einsamkeit
Steigt's wie wunderbares Singen-
O du gnadenreiche Zeit!
Merry Christmas commit ;)

Added reward parsing:
* Transition-based rewards are parsed using the existing (Deterministic)SparseTransitionsParser.
* State-based rewards are parsed using a new SparseStateRewardParser that parses lines consisting of a state and an associated reward.
* The Dtmc class now stores the two reward models.
* The DtmcParser class now parses up to one transition-based and one state-based reward file. They may, however, be omitted in which case the respective reward model is set to null.

Added DtmcParser class that parses a whole DTMC, making use of the
labeling and transitions parser.
Removed the parseDtmc function from IoUtility, as it became obsolete
with the DtmcParser class, fitted test cases accordingly.
