Abstract
We present a new circumscription method, called discriminant circumscription, for first order theories described by clauses whose orientations are of primary importance in their applications. These applications have been primarily dominated by deductive databases and logic programs. We show that discriminant circumscription is equivalent to the stable model semantics of deductive databases. This method is therefore strictly more powerful than those previously proposed by Przymusinski and by Lifschitz.
