Abstract

We show a reduction to propositional logic from a Boolean combination of inequalities of the form vi 驴 vj + c and vi vj + c, where c is a constant and vi, vj are variables of type real or integer. Equalities and uninterpreted functions can be expressed in this logic as well. We discuss the advantages of using this reduction as compared to competing methods, and present experimental results that support our claims.
