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...
We present a unifying approach to the efļ¬cient evaluation of propositional answer-set programs. Our approach is based on backdoors which are small sets of atoms that represent ā...
Abstract. The problem of merging multiple sources information is central in several domains of computer science. In knowledge representation for artiļ¬cial intelligence, several a...
We propose an extension of answer sets, that we call safe beliefs, that can be used to study several properties and notions of answer sets and logic programming from a more genera...
Abstract. We consider the problem of whether a given preferred answer set program can be reduced to a propositional formula. Research on this topic is of both theoretical and pract...
