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 3158d19123 Started working on adapting LP solver interface to new expressions.

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.

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.

dehnert a0df98a6eb Removed unnecessary virtual keyword in Expression class.

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.

dehnert c6976dd8b5 Added some query methods for new expression classes.

dehnert 83f9832e2d Added type check visitor to validate types of identifiers in expressions. Started writing validation method on PRISM program class.

dehnert 311247ff0c Added support for Xor in expression classes and added parsing functionality for Xor, Implies and Iff.

dehnert cc625a2e00 Added a ton of ifndefs, because MSVC does not yet support defaulting move constructors/assignments.

dehnert 7667933caf First working version of explicit model generation using the new PRISM classes and expressions.
11 years ago
dehnert 199b6576a9 Added ternary operator. Parsing standard PRISM models into the PRISM classes now works. Included tests for parsing stuff. ToDo: add remaining semantic checks for parsing/PRISM classes and fix explicit model adapter.

dehnert f6587b424d Further work on PrismParser and the related PRISM classes...
11 years ago
dehnert 7610bc8e76 Started reducing the complexity in the PRISM grammar.
11 years ago
dehnert d87c79d0f6 Added implies/iff to expression classes. Finished reworking PRISM classes.

dehnert 6e1241211b Started moving IR and adjusting it to the new expression classes.
11 years ago
dehnert 8af52c8866 Finished new expression classes and corresponding functional tests.
11 years ago
dehnert c8b5897cff Designed interface of expression classes and started implementing it.
11 years ago
dehnert 1d6c25547b Further work on new expressions.
11 years ago
dehnert 47b0f0b068 Further (preliminary) work on expression classes.
