We show that the concepts of strong and uniform equivalence of logic programs eneralized to an abstract algebraic setting of operators on complete lattices. Our results imply char...

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 consider the simplification of logic programs under the stablemodel semantics, with respect to the notions of strong and uniform equivalence between logic programs, r...
