12 years ago
dehnert 35d16a1191 Replaced VectorSet bei boost::container::flat_set, which does essentially the same. Fixed a bug in sparse matrix creation.
12 years ago
dehnert f684ce7799 Removed obsolete constructors of sparse matrix class as the new matrix builder is supposed to be used anyway. Fixed some minor issues.
12 years ago
dehnert 5e12a65d67 Adapted performance-critical iterations in graph utility to the iterator formulation with less overhead.
12 years ago
dehnert 72531bcebb Added proper TBB multi-threading to all operation relevant to model checking MDPs.
12 years ago
dehnert cdc369b96a Temporarily removed the detection of the repository version of TBB from CMakeLists.txt. Corrected TBB sparse matrix-vector multiplication. Added TBB parallel vector addition.
12 years ago
dehnert 81cf0e2b22 Added SparseMatrixBuilder class that actually builds the matrices. A call to build() will then generate the matrix. This eliminates superfluous checks in the matrix that slowed down performance.
12 years ago
dehnert cf2b84b281 Further work on iterators for sparse matrix.
12 years ago
dehnert a26f63be30 Finished reworking the sparse matrix implementation. Adapted all other classes to the (partially) new API of the matrix.
12 years ago
dehnert 8a47d03cf7 Started to rework the interface of the sparse matrix class.
12 years ago
dehnert 84bd5f3b40 Renamed ConstTemplates to constants. Removed all calls to constGetZero, constGetOne and constGetInfinity by the new names. Created performance test for bit vector iteration.
12 years ago
dehnert 30322ec57d Now officially made the iterator over bit vectors an input iterator so that it can be used for constructing STL containers and other containers.
12 years ago
dehnert 344e1b6dd3 Enabled checking of some untimed properties on Markov automata.
12 years ago
dehnert b3601782a9 Added Lp Solver class for glpk and added it as an option in CMakeLists.txt.
12 years ago
dehnert 0a89d65f93 Started refactoring Markov automaton model checker.
12 years ago
dehnert 18711c01a3 First working version of time-bounded reachability for Markov automata.
12 years ago
dehnert ea7f48cff6 Introduced solver header in utility to return standard solvers when requested.
12 years ago
masawei 170306e46d Moved SparseMatrix transposition function from AbstractModel (named: getBackwardsTransitions) to SparseMatrix (named: transpose) where it belongs.
12 years ago
dehnert 9e941e6b4a Added scheduler classes. Added method to model classes that applies a scheduler.
12 years ago
dehnert 09f192b40f Refactored SCC-Decomposition design as a preparation step for computing maximal end components of Markov automata.
12 years ago
dehnert cebda374d1 Further step towards Markov automata parser.
12 years ago
dehnert 4550422fac Added formula support for PRISM models. ExplicitModelAdapter now properly checks for out-of-bound values for integer variables.
12 years ago
dehnert 78d5f89ea2 Added formula support for PRISM models. ExplicitModelAdapter now properly checks for out-of-bound values for integer variables.
12 years ago
