An Experimental Study of Search Strategies and Heuristics in Answer Set Programming
Answer Set Programming (ASP) and propositional satisfiability (SAT) are closely related. In some recent work we have shown that, on a wide set of logic programs called “tight”...

Solving satisfiability problems with preferences
Abstract. Propositional satisfiability (SAT) is a success story in Computer Science and Artificial Intelligence: SAT solvers are currently used to solve problems in many different ...

Translating Pseudo-Boolean Constraints into SAT
In this paper, we describe and evaluate three different techniques for translating pseudoboolean constraints (linear constraints over boolean variables) into clauses that can be h...

A Translation of Pseudo Boolean Constraints to SAT
This paper introduces a new CNF encoding of pseudo-Boolean constraints, which allows unit propagation to maintain generalized arc consistency. In the worst case, the size of the p...

On Resolution Proofs for Combinational Equivalence
Modern combinational equivalence checking (CEC) engines are complicated programs which are difficult to verify. In this paper we show how a modern CEC engine can be modified to pr...
