A satisfiability procedure for quantified boolean formulae
The renesse issue on satisfiabilityWe present a satisfiability tester QSAT for quantified Boolean formulae and a restriction QSATCNF of QSAT to unquantified conjunctive normal form formulae. QSAT makes use of procedures which replace subformulae of a formula by equivalent formulae. By a ...
Satisfiability of mixed Horn formulas
In this paper the class of mixed Horn formulas is introduced that contain a Horn part and a 2-CNF (conjunctive normal form) (also called quadratic) part. We show that SAT remains NP-complete for such instances and also that any CNF formula can be ...
Backjumping for quantified Boolean logic satisfiability
The implementation of effective reasoning tools for deciding the satisfiability of Quantified Boolean Formulas (QBFs) is an important research issue in Artificial Intelligence. Many decision procedures have been proposed in the last few years, most of ...
