A variable is local if it occurs in a clause body but not in its head. Local variables appear naturally in practical logic programming, but they complicate several aspects such as ...
Unfold/fold transformation systems for logic programs have been extensively investigated. Existing unfold/fold transformation systems for normal logic programs allow only Tamaki-Sa...

Abstract: This paper describes the application of CLP (constraint logic programming) to several digital circuit design problems. It is shown that logic programming together with ef...
Abstract. Among others, Alferes et al. (1998) presented an approach for updating logic programs with sets of rules based on dynamic logic programs. We syntactically redefine dynami...

Abstract. In Datalog, missing values are represented by Skolem constants. More generally, in logic programming missing values, or existentially quantified variables, are represent...
