Much work has been done on extending the well-founded semantics to general disjunctive logic programs and various approaches have been proposed. However, no consensus has been reac...
Abstract. In this paper we consider a logic programming framework for reasoning about imprecise probabilities. In particular, we propose a new semantics, for the Probabilistic Logi...
We define the semantics of logic programs with (abstract) constraint atoms in a way closely tied to default logic. Like default logic, formulas in rules are evaluated using the cl...
This paper discusses the background, algorithms and implementation techniques to support programmers in ‘debugging’ logic programs under the answer set semantics. We first inv...
