Abstract. We introduce the first substantial approach to preprocessing in the context of answer set solving. The idea is to simplify a logic program while identifying equivalences ...
Loops and the corresponding loop formulas play an important role in answer set programming. On the one hand, they are used for guaranteeing correctness and completeness in SAT-base...
The main contribution of this paper is the definition of the preference description language ¡¢ . This language allows us to combine qualitative and quantitative, penalty bas...
