This paper outlines a novel approach to the computation of answer sets in an evolving and interactive environment. Instead of recomputing the semantics of the entire program, our a...
By QoS (Quality of Service), we often refer to a set of quality requirements on the collective behavior of one or more objects. These requirements enable the provision of better se...
Abstract. We present an integration of answer set programming and constraint processing as an interesting approach to constraint logic programming. Although our research is in a ve...
A relational database is inconsistent if it does not satisfy a given set of integrity constraints. Nevertheless, it is likely that most of the data in it is consistent with the co...

We present a general method to improve computation of answer sets by analyzing structural properties of normal logic programs. Therefore we use labeled directed graphs associated t...
