dehnert 7ea6ec3644 Further refactoring.

dehnert ab58103555 Started to pimp matrix. First step: added proper methods setColumn/setValue that operate on a matrix entry and removed the non-const versions of getColumn/getValue. Added a typedef for the index type in the matrix so that it becomes possible to have matrices with a different index type (e.g. 32-bit values).

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 5d53c6efa5 Added ODD-concept to easily convert between DD-based and explicit formats.
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 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.
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 6f9dd7107d Added universal abstraction function to DD layer.
11 years ago
dehnert 8d3ed7d2fa Added min/max functions on DDs. Added tests for them and ite operation.
11 years ago
dehnert 5b06259a05 Added ite operator for DDs in abstraction layer.
11 years ago
dehnert 6078e07476 First version of DD iterator; small test included.
11 years ago
dehnert 5fe7ffe51a Added missing function declaration in CUDD'c C++ interface. Started on an iterator for DD valuations.
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
dehnert 6e1241211b Started moving IR and adjusting it to the new expression classes.
11 years ago
dehnert 88d9f36ef4 Added min/max abstract over DD variables to CUDD (actual code taken from PRISM). Added more tests for DD layer. Fixed some bugs in the DD layer.
11 years ago
dehnert 0fce0444f7 Further bugfixes and tests for DD layer.
11 years ago
dehnert cf5c04065e Added streaming functionality to DD. More tests, more bugfixes.
11 years ago
dehnert a4fec9f080 Started writing functional tests for DD abstraction layer and fixed some bugs on the way.

dbohlender 7ea7ce93e2 Fixed MSVC incompabilities
11 years ago
dehnert cb35b3315d Added matrix-matrix multiplication to DD interface. (This includes matrix-vector multiplication as a special case).
