2018-02-02Option to check solutions produced by SyGuS solver (#1553)Haniel Barbosa
2018-02-01Add interface in sygus to get synthesis solution Nodes (#1552)Andrew Reynolds
2018-02-01Use sygus to synthesize/verify rewrite rules (#1547)Andrew Reynolds
2018-01-30Further clean and document datatypes rewriter (#1548)Andrew Reynolds
2018-01-29Generalize explanations for PBE sygus strings based on negative contains ↵Andrew Reynolds
when multiple strategies are present (#1546)
2018-01-28Sort children of all commutative operators for sygus. (#1544)Andrew Reynolds
2018-01-27Removing an unused variable. Resolves CID 1172257. (#1542)Tim King
2018-01-26Removing structurally dead code. (#1540)Tim King
2018-01-24Commenting out throw specifiers on SmtEngine. These can later be refined ↵Tim King
into better documentation. (#1512)
2018-01-24Added unit tests for PLUS, NEG, NOT ICs for CBQI BV. (#1534)Aina Niemetz
2018-01-23Fix MULT handling for CBQI BV. (#1531)Aina Niemetz
2018-01-23Commenting out throw specifiers for DeltaRationExceptions. These functions ↵Tim King
can be cleaned up later. (#1529)
2018-01-22Add previous concat handling for CBQI BV as heuristic for EQ. (#1528)Aina Niemetz
Previously, we computed an inverse for s1 o x, x o s2, s1 o x o s2 while disregarding that invertibility depends on si. This adds this handling as an optional heuristic for concats over (dis)equality since it improves performance on a considerable number of benchmarks.
2018-01-21Refactor and fix solveBvLit for CBQI BV. (#1526)Aina Niemetz
This refactors and simplifies solveBvLit() and fixes the following: - generate side conditions for BITVECTOR_NEG, BITVECTOR_NOT, BITVECTOR_PLUS, BITVECTOR_XOR over inequalities and disequality - fix CONCAT handling (generate side conditions rather then computing an inverse which was incorrect) - fix SIGN_EXTEND handling (same as with CONCATs)
2018-01-21Only push/pop around check-sat if it is associated with an assertion (#1525)Andrew Reynolds
2018-01-17Removes yet more throw specifiers. Updating the documentation as needed. (#1518)Tim King
2018-01-15Removing more miscellaneous throw specifiers. (#1509)Tim King
Removing more miscellaneous throw specifiers. Also fixing the spelling of amount in several places.

2018-01-12Improvements for CBQI BV (#1504)Andrew Reynolds
2018-01-10Removed division by constant handling for CBQI BV (unsound). (#1508)Aina Niemetz
This removes division by constant handling in the BV inverter introduced in #1498. Division by constant was simplified to: x / s OP t ---> x = t / s^-1 if s odd and there exists a multiplicative modular inverse s^-1. This however, is incorrect since x / s * 1 / s^-1 != x / (s * s^-1)

2018-01-07Removes RationalFromDoubleException. Replaces this with an explicit M… (#1476)Tim King
* Removes RationalFromDoubleException. Replaces this with an explicit Maybe<Rational> datatype. Makes Maybe<T> CVC4_PUBLIC. Updates the users of Rational::fromDouble(). Miscellaneous cleanup of ApproxSimplex.
2018-01-06Removing throw specifiers from src/parser/. (#1486)Tim King

2018-01-04Add side conditions for inequalities of SHL. (#1472)Mathias Preiner
2018-01-04Improvements for CBQI (#1478)Andrew Reynolds
Includes: - Basic rewriting for choice functions in the builtin rewriter, - Do not consider more than one equal term in ceg instantiator (helps cases where we have a repeated pattern of duplicate instantiations), - Do not introduce dummy extract equalities in the cbqi-bv-rm-extract pass (dummy concat equalities suffice). - Do not consider extracts in nested quantified formulas in the cbqi-bv-rm-extract pass.
