We propose a parametric introduction of intensionally defined sets into any CLP(D) language. The result is a language CLP({D}), where constraints over sets of elements of D and over sets of sets of elements, and so on, can be expressed. The semantics of CLP({D}) is based on the semantics of logic programs with aggregates and the semantics of CLP over sets. We investigate the problem of constraint resolution in CLP({D}) and propose algorithms for constraints simplification.

Abstract: | We propose a parametric introduction of intensionally defined sets into any CLP(D) language. The result is a language CLP({D}), where constraints over sets of elements of D and over sets of sets of elements, and so on, can be expressed. The semantics of CLP({D}) is based on the semantics of logic programs with aggregates and the semantics of CLP over sets. We investigate the problem of constraint resolution in CLP({D}) and propose algorithms for constraints simplification. |
