Answer Set Planning (Abstract)

In “answer set programming”[5,7] solutions to a problem are represented by answer sets (known also as stable models), and not by answer substitutions produced in response to a query, as in conventional logic programming. Instead of Prolog, answer set programming uses software systems capable of computing answer sets. Four such systems were demonstrated at the Workshop on Logic- Based AI held in June of 1999 in Washington, DC: dlv1, smodels,2, DeReS3 and ccalc4.
