2010-05-31 | First draft implementation of mkAssociative | Christopher L. Conway | |
2010-05-29 | Adding a couple of example from fuzzsmt to regress1. | Tim King | |
2010-05-29 | Couple of fixes to theory arith. pivotAndUpdate now multiplies by a_kj. And ↵ | Tim King | |
the tableau now simulates older pivots while adding a new row. | |||
2010-05-29 | After blasting the disjuncts, TheoryEngine rewrite needs to reinvoke itself. ↵ | Tim King | |
QF_LRA is now no longer complaining about seeing nodes that can be rewritten to CONST_BOOLEAN. | |||
2010-05-28 | This update enables TheoryArith to accept assertions that rewrite to true or ↵ | Tim King | |
false. This is temporary and will be removed once TheoryEngine rewriting is more fully debugged. | |||
2010-05-28 | Bug fixes for combining coefficients of rewritten nodes. | Tim King | |
2010-05-28 | Added printModel() to src/theory/arith/partial_model.cpp. This is a ↵ | Tim King | |
debugging utility that prints out the lower bound, upper bound, assignment, and the constraints that were asserted that caused the lower bound and upperbound to be asserted. | |||
2010-05-28 | A few changes to the organization of TheoryEngine rewriting. A few bug fixes ↵ | Tim King | |
for it as well. make check should now work again. | |||
2010-05-28 | Moving the ITE removal from CnfStream to TheoryEngine, which is a bit closer ↵ | Tim King | |
to its final destination. Added a basic rewriter to TheoryUF. (x=x rewrites to true.) Added DIVISION to src/expr/node_manager.cpp's getType. Fixed the theory returned for variables in theoryOf() for bool and arith. Fixed TheoryEngine rewrite children to properly handle APPLY_UFs. Removed the special case for equality in TheoryEngine rewrite. A few tests are currently broken due to deallocation errors. Morgan and I will try to commit a fix to this in a little bit. | |||
2010-05-27 | fix bug #134: infinite deallocation loop | Morgan Deters | |
2010-05-27 | small cosmetic change to tests summary output | Morgan Deters | |
2010-05-27 | Remove isAtomic() as per 4/27/2010 meeting. Add comments about its ↵ | Morgan Deters | |
potential design for later. Resolves bug 113, invalidates bugs 93 and 94. | |||
2010-05-27 | fix compiler comparison-signedness warnings | Morgan Deters | |
2010-05-27 | Reverting this file to not include any comments. (Morgan's revision and my ↵ | Tim King | |
revision were in conflict.) | |||
2010-05-27 | added the ability to add custom expected stdout, stderr, and exit codes to ↵ | Morgan Deters | |
smt and smt2 regressions; resolves bug 132 | |||
2010-05-27 | Preregistration has been turned on. Highly experimental eager splitting ↵ | Tim King | |
support has been added. Also a few bug fixes to Tableau. | |||
2010-05-27 | Use the newer automake test driver "parallel-tests". This driver: | Morgan Deters | |
* keeps test logs around * provides parallel testing functionality (with make -jN). I've also added new functionality in test/Makefile.am which deletes old test logs, ensures that ALL tests are tried (even if units fail), and provides a color-coded summary at the end of the test run, which shows how many units, regressions (per level), and system tests failed (or passed), and provides a link to the log file for further information. Resolves bug 117. | |||
2010-05-27 | Adding debug assertions on most TNode operations | Christopher L. Conway | |
2010-05-27 | Adding NodeManager::prepareToBeDestroyed() (Fixes: #128) | Christopher L. Conway | |
2010-05-27 | Adding .cvc4_config to .gitignore | Christopher L. Conway | |
2010-05-27 | fix bug #111: errors in building lcov-all | Morgan Deters | |
2010-05-27 | fix bug 120; competition mode regression failures for intentionally-buggy input | Morgan Deters | |
2010-05-26 | . '+Outstanding case split in theory arith' | Tim King | |
2010-05-26 | Adding CnfStreamBlack tests for all Boolean connectives | Christopher L. Conway | |
2010-05-26 | Fixing test failures in CnfStreamBlack (it was the test's fault) | Christopher L. Conway | |
2010-05-26 | Adding documentation to my-configure | Christopher L. Conway | |
2010-05-26 | Fixing my-configure | Christopher L. Conway | |
2010-05-26 | Adding contrib/my-configure | Christopher L. Conway | |
2010-05-26 | Adding CnfStream unit tests | Christopher L. Conway | |
2010-05-26 | CDMap<> and CDOmap<> fixes to resolve bug 123 | Morgan Deters | |
2010-05-26 | Fix for bug 131. Added some additional debugging assertions for the arith ↵ | Tim King | |
rewriter. | |||
2010-05-26 | CDMap: fix bug 130 | Morgan Deters | |
2010-05-26 | Prevent lexer errors being raised if a parser error is pending. | Christopher L. Conway | |
This fixes a bug Dejan has often whined about but never filed. | |||
2010-05-25 | Added Rational constructors that only take a numerator. The const char* ↵ | Tim King | |
Rational and Integer constructors are now explicit. This means that 'Integer = 3;' and so on are no longer permitted. This closes bug 121. | |||
2010-05-25 | Some initial changes to allow for lemmas on demand. | Dejan Jovanović | |
To be done: * Add erasable map Clause* to bool to minisat (backtracks with the solver) * Add map from Clause* to Node (clauses that came from a node) * Add reference counting Literal -> Node to CNFManager * If Literal -> Node refcount goes to zero, the clauses of Node can be erased (if eresable) * If clause is erased for each L in clause L -> Node refcount goes down | |||
2010-05-21 | Small fixes to TheoryArith. Added a hack to make Integers a subtype of ↵ | Tim King | |
Real. See Bug 127 for a discussion of the hack. I am also adding a regression test that does not work (bug 128). It is not enabled so make check should still be fine. | |||
2010-05-20 | Added the division symbol to the parser, and minimal support for it in ↵ | Tim King | |
TheoryArith. Also directly hacked in support for theoryOf() to work for equalities where the left hand is a variable of type real. | |||
2010-05-19 | Significant revision to theory/arith. The new draft has a lot of small bug ↵ | Tim King | |
fixes and organizational changes. The theory is now enabled to perform checking in the TheoryEngine. This draft can now solve 2 new regression tests test/regress/regress0/ineq_slack.smt and test/regress/regress0/ineq_basic.smt. There is also a small bug fix inside src/expr/attribute.h. | |||
