In this paper, we consider an approach to update nonmonotonic knowledge bases represented as extended logic programs under the answer set semantics. In this approach, new informat...

In this paper we show that an arbitrary propositional theory, when interpreted under the answer sets semantics (called Equilibrium Logic for this general syntax), can always be re...

Abstract We study the notion of strong equivalence between two disjunctive logic programs under the G3-stable model semantics, also called the P-stable semantics, and we show how s...
