dehnert caf96c04e0 Extended DD interface by methods to generate explicit row-grouped matrices from DDs.
11 years ago
dehnert 8587f68eb1 Fixed toMatrix conversion using ODDs. The next step is to generate non-deterministic matrices, i.e., matrices with row groups.
11 years ago
dehnert 236e7fa290 Another step towards generating explicit data structures from DDs using ODDs.
11 years ago
dehnert f12ff82baf Added getNodeCount for ODD and fixed a bug concerning boolean meta variables.
11 years ago
dehnert 5d53c6efa5 Added ODD-concept to easily convert between DD-based and explicit formats.
11 years ago
dehnert 72cc5f2188 Added 'power' as a binary operator in expression classes and expression grammar.
11 years ago
PBerger 03399375f8 Fixed an unintended 32bit shift being expanded to 64 bit
11 years ago
dehnert 7b2def2b11 Added function to retrieve the minterms of a DD as an expression and added corresponding test.
11 years ago
dehnert 60b2145461 Added function to DD interface that creates a nested if-then-else expression that represents the very same function as the DD. Added a test for this functionality. Added some methods offereded by Cudd to simplify DDs.
11 years ago
masawei 3271e73f01 Fixed the last test. All tests green now (well, except the ones that need gurobi, which I don't have).
11 years ago
masawei 9a28e5b580 Added proper formula string method to filters.

David_Korzeniewski a0319cb6e7 Model Generation and Tests for translating from z3 to storm
11 years ago
David_Korzeniewski 79984db3ee Added test for checkWithAssumptions

David_Korzeniewski 9a7b4f69ef More tests and some small bugfixes for Z3SmtSolver

David_Korzeniewski 45bc8ea665 Conditional compilation for all parts using z3 by checking STORM_HAVE_Z3
11 years ago
masawei 4bf0299279 Changed the Prctl/Csl formula parsers to be static classes.
11 years ago
dehnert 45486600f7 Made parts of the interface of the DdManager protected (because they shouldn't be accessible from the outside world).
11 years ago
dehnert 29d8111991 Adapted Gurobi and glpk LP solvers to expression-based interface. Adapted tests and made them work again.
11 years ago
dehnert 389fddc996 Added some more methods to valuations. Changed visitor invocation slightly. Moves ExpressionReturnType in separate file. Finished linearity checking visitor. Started on visitor that extracts coefficients of linear expressions.
11 years ago
dehnert 57a8381f91 If requested, the DD iterator can now skip meta variables which are 'don't cares' for the function value.
11 years ago
dehnert db232fe39b Moved from pair to MatrixEntry as the basic building block of the matrix. Now matrix elements can be accessed in a more readable way.
11 years ago
dehnert 92ee6187fa Added more query methods to expressions. SparseMatrix now keeps track of non zero entries and models show correct number of transitions by referring to nonzero entries rather than all entries in the matrix.
11 years ago
dehnert 219af9b43b Removed constants from expressions. Even though PRISM has the concept of constants and variables, it currently makes no sense to distinguish them in our expression classes.
11 years ago
dehnert c6976dd8b5 Added some query methods for new expression classes.
11 years ago
dehnert c76e0e8d4d Added class for initial construct of PRISM programs (to capture position information). Added more validity checks for programs and tests for them (not all though).
11 years ago
dehnert 82836f1ad1 Added some checks for validity of identifiers in PRISM programs. Added some illegal tests to test suite.
11 years ago
dehnert 8d3ed7d2fa Added min/max functions on DDs. Added tests for them and ite operation.
11 years ago
dehnert 39ec9401ef Fixed the PrismParser so the exact format of PRISMs boolean expressions can now be parsed.
11 years ago
dehnert 6078e07476 First version of DD iterator; small test included.
11 years ago
PBerger 1d8ae9fc89 Fixed an issue with templated variadic template arguments (see http://stackoverflow.com/questions/23119273/use-a-templated-variadic-template-parameter-as-specialized-parameter for discussion)
11 years ago

11 years ago
dehnert 61d4bb956c Added functionality to compare two ADDs up to a given precision. Added logical operator overloads to DD interface. Added tests for all new features.
11 years ago
dehnert 5a4730ae22 When exporting DDs to the dot format, edges leading to the zero node are now suppressed. Also, nodes in the dot file are now labeled with variable names (+ the number of the bit).
11 years ago
PBerger 94b25c02ca Fixed bugs in some files.
11 years ago
