| Abstract(in English) | In computing circumscription by logic programming, circumscription is usually transformed into some target logic program whose answer sets yield the Herbrand models of circumscription. In this paper, we propose a new method of computing models of prioritized circumscription in answer set programming, which is correct and more efficient than previous approaches. The basic idea of our approach is to transform a given circumscription into a general extended disjunctive program whose answer sets (if exist) yield strictly preferred models to a given candidate model with respect to the preorder≦P^1>・・・>P^k;Z. Hence its inconsistency enables us to determine models of prioritized circumscription. We also show the soundness and completeness theorems for our method. Based on our new method, a circumscriptive model generator has already been implemented, and the preliminary experimental results are encouraging. |
