dehnert 7b2def2b11 Added function to retrieve the minterms of a DD as an expression and added corresponding test.
11 years ago
dehnert e79fa50999 Changed naming of DD variables belonging to one meta variable slightly: only integer-valued meta variables now get a '.i' suffix to denote their i-th bit.
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
dehnert 1513241985 Added functions for more efficiently retrieving the DD for 'greater than constant', 'greater or equal than constant' and 'notZero'.
11 years ago
dehnert b1f22c1747 Added shortcut DD interface to compute \'greaterZero\' on a DD.

dehnert 6a2d75d68d Some changes in anticipation of integrating MEDDLY.
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
David_Korzeniewski 37ef3feebb Fixed return type of addBinaryVariable
11 years ago
David_Korzeniewski 4e6c9b7d6b Implemented translating z3 expressions to storm expressions
11 years ago
dehnert 66d6fa3bb4 Fixed wrong type.

David_Korzeniewski c3a71d5915 Merge branch 'master' into SmtSolvers
11 years ago
dehnert 686618e6e2 Added missing header to (hopefully) fix MSVC problems.
11 years ago
dehnert 9e746549a8 Fully adapted MILP-based counterexample generator to new LP solver interface.
11 years ago
dehnert db4721ce3a Started adapting MILP-based counterexample generator to new LP solver interface.
11 years ago
dehnert d80586b4aa Adapted MA model checker to new LP solver interface (LRA computation).
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 d5c2f9248f Finished linear coefficient visitor and adapted glpk solver to new expression-based LP solver interface.
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.

dehnert ab89716286 Merge branch 'master' into lpsolverInterface
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 f60ea09cf4 Valuations now have methods to check whether they contain a given identifier.
11 years ago
dehnert 024b98978f Made internal changes to SimpleValuations to (hopefully) make it nice and fast.
11 years ago
dehnert 3158d19123 Started working on adapting LP solver interface to new expressions.
11 years ago
dehnert 9d3e78ab89 Cudd now gets 2GB instead of 2MB by default.
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 2d8cc2efcd Added reordering functionality to DD interface.
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
David_Korzeniewski 29083cc89c Implemented asserting expressions and checking satisfiability with z3
11 years ago
David_Korzeniewski 83d2a1c315 Adapted Z3ExpressionAdapter to deletion of constant expressions. Added functionality to autocreate variables in the solver. Added function to get variables and their types from an expression.

David_Korzeniewski 98f87a5e6d Adapted Z3ExpressionAdapter for new expressions
11 years ago
dehnert a0df98a6eb Removed unnecessary virtual keyword in Expression class.
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.
