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...
Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check” nature ...
In recent research on nonmonotonic logic programming, repeatedly strong equivalence of logic programs P and Q has been considered, which holds if the programs P ∪ R and Q ∪ R h...
Abstract. We define a translation of aggregate programs to normal logic programs which preserves the set of partial stable models. We then define the classes of definite and str...
In this paper we analyze the relationship between cyclic definitions and consistency in GelfondLifschitz's answer sets semantics (initially defined as `stable model semantics...
