On the Role of Negation in Choice Logic Programs
We introduce choice logic programs as negation-free datalog programs that allow rules to have exclusive-only (possibly empty) disjunctions in the head. Such programs naturally mod...

Constraint Model Elimination and a PTTP-Implementation
In constraint logic programming, proof procedures for Horn clauses are enhanced with an interface to efficient constraint solvers. In this paper we show how to incorporate constra...
