A New Perspective on Stable Models

Download www.cs.utexas.edu

The deﬁnition of a stable model has provided a declarative semantics for Prolog programs with negation as failure and has led to the development of answer set programming. In this paper we propose a new deﬁnition of that concept, which covers many constructs used in answer set programming (including disjunctive rules, choice rules and conditional literals) and, unlike the original deﬁnition, refers neither to grounding nor to ﬁxpoints. Rather, it is based on a syntactic transformation, which turns a logic program into a formula of secondorder logic that is similar to the formula familiar from the deﬁnition of circumscription.
