We define a reduction system Ë¿ which preserves the stable semantics. This system includes two types of transformation rules. One type (which we call ˾) preserves the stable...

We develop an Answer Set Programming formalism based on Default Logic. We show that computing generating sets of extensions in this formalism captures all ΣP 2 search problems.
Open answer set programming (OASP) is an extension of answer set programming where one may ground a program with an arbitrary superset of the program’s constants. We define a ...

This paper studies compositional semantics of nonmonotonic logic programs. We suppose the answer set semantics of extended disjunctive programs and consider the following problem. ...
Abstract. A novel declarative approach of forgetting in answer set programming (ASP) has been proposed recently. In this paper we report a system prototype of forgetting in ASP, ca...
