The notion of strong equivalence on logic programs with answer set semantics gives rise to a consequence relation on logic program rules, called SE-consequence. We present a sound...

In previous work we have discussed the importance of identifying the cycles that occur in a logic program under the answer set semantics, and the connections between cycles, that w...

Abstract. We extend the open answer set semantics for programs with generalized literals. Such extended programs (EPs) have interesting properties, e.g. the ability to express infi...

Abstract. We present an approximation theory for the extended answer set semantics, using the concept of an approximation constraint. Intuitively, an approximation constraint, whil...

Abstract. A novel declarative approach of forgetting in answer set programming (ASP) has been proposed recently. In this paper we report a system prototype of forgetting in ASP, ca...

In this paper we introduce an extension of Equilibrium Logic (a logical characterisation of the Answer Set Semantics for logic programs) consisting in the inclusion of modal tempor...

In many cases, a logic program can be divided into two parts, so that one of them, the \bottom" part, does not refer to the predicates de ned in the \top" part. The \bot...
