Dynamic updates of non-monotonic knowledge bases
In this paper we investigate updates of knowledge bases represented by logic programs. In order to represent negative information, we use generalized logic programs which allow de...

Loop Formulas for Disjunctive Logic Programs
Abstract. We extend Clark’s definition of a completed program and the definition of a loop formula due to Lin and Zhao to disjunctive logic programs. Our main result, generaliz...

Transforming co-NP Checks to Answer Set Computation by Meta-Interpretation
Many NP-complete problems can be encoded in the answer set semantics of logic programs in a very concise way, where the encoding reflects the typical “guess and check” nature ...
