Advanced Preprocessing for Answer Set Solving
Abstract. We introduce the first substantial approach to preprocessing in the context of answer set solving. The idea is to simplify a logic program while identifying equivalences ...

A Reductive Semantics for Counting and Choice in Answer Set Programming
In a recent paper, Ferraris, Lee and Lifschitz conjectured that the concept of a stable model of a first-order formula can be used to treat some answer set programming expressions...

Communicating Answer Set Programs
Answer set programming is a form of declarative programming that has proven very successful in succinctly formulating and solving complex problems. Although mechanisms for represen...

Effect of knowledge representation on model based planning: experiments using logic programming encodings
In this paper we implement planning using answer set programming. We consider the action language A and its extensions. We show that when the domain is described using richer feat...

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

On the Existence of Answer Sets in Normal Extended Logic Programs
An often problematic feature in answer set programming is that a program does not always produce an answer set, even for programs which represent default information in a seemingl...

Splitting a Logic Program
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...

plp: A Generic Compiler for Ordered Logic Programs
Abstract This paper describes a generic compiler, called plp, for translating ordered logic programs into standard logic programs under the answer set semantics. In an ordered logi...

Computing Weighted Solutions in Answer Set Programming
For some problems with many solutions, like planning and phylogeny reconstruction, one way to compute more desirable solutions is to assign weights to solutions, and then pick the ...

Manifold Answer-Set Programs for Meta-reasoning
Abstract. In answer-set programming (ASP), the main focus usually is on computing answer sets which correspond to solutions to the problem represented by a logic program. Simple re...
