Algorithms for testing the satisfiability of propositional formulae

Abstract

It is experimentally shown that the satisfiability for Horn clauses algorithm (Dowling, Gallier) is efficient. The authors propose two relaxation schemes which map instances of a satisfiability problem for propositional formulae into problem instances for Horn clauses. One of the resulting algorithms runs in experiments several times faster than the Davis-Putnam algorithm.

Keywords

efficiency, Logic, Analysis of algorithms and problem complexity, satisfiability for Horn clauses algorithm, Theorem proving (deduction, resolution, etc.)
