An important issue towards a broader acceptance of answer-set programming (ASP) is the deployment of tools which support the programmer during the coding phase. In particular, met...
We first provide a mapping from Pearce’s equilibrium logic and Ferraris’s general logic programs to Lin and Shoham’s logic of knowledge and justified assumptions, a nonmon...
Logic programming under the answer-set semantics nowadays deals with numerous different notions of equivalence between programs. This is due to the fact that equivalence for substi...
We present a unifying approach to the efficient evaluation of propositional answer-set programs. Our approach is based on backdoors which are small sets of atoms that represent ...
Answer-set programming (ASP) is a well-acknowledged paradigm for declarative problem solving, yet comparably little effort has been spent on the investigation of methods to support...
