The definition of a stable model has provided a declarative semantics for Prolog programs with negation as failure and has led to the development of answer set programming. In th...
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...
Developing scalable coordination algorithms for multi-agent systems is a hard computational challenge. One useful approach, demonstrated by the Coverage Set Algorithm (CSA), explo...
We consider the problem of answering datalog queries using materialized views. The ability to answer queries using views is crucial in the context of information integration. Prev...
