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...
We propose and study extensions of logic programming with constraints represented as generalized atoms of the form C(X), where X is a finite set of atoms and C is act constraint (...
Abstract. We present a framework for updating logic programs under the answer-set semantics that builds on existing work on preferences in logic programming. The approach is simple...
Disjunctive Logic Programming (DLP) under the consistent answer set semantics is an advanced formalism for knowledge representation and reasoning. It is, under widely believed assu...
Suppose we are given a set W of logical structures, or possible worlds, a set of logical formulas called possible data and a logical formula . We then consider the classification p...
