Stable models and circumscription

Stable models and circumscription
The concept of a stable model provided a declarative semantics for Prolog programs with negation as failure and became a starting point for 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 and, unlike the original definition, refers neither to grounding nor to fixpoints. It is based on a syntactic transformation similar to parallel circumscription. Key words: Answer set programming, Circumscription, Nonmonotonic reasoning, Program completion, Stable models
