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...
Abstract. Often graphs are used to investigate properties of logic programs. In general, different graphs represent different kinds of information of the corresponding programs. ...
Abstract. Nested logic programs and epistemic logic programs are two important extensions of answer set programming. However, the relationship between these two formalisms is rarel...
nlp is a compiler for nested logic programming under answer set semantics. It is designed as a front-end translating nested logic programs into disjunctive ones, whose answer sets ...

Equilibrium logic, introduced by David Pearce, extends the concept of an answer set from logic programs to arbitrary sets of formulas. Logic programs correspond to the special case...
