This is a summary of [PCHS12], where a framework to combine tabling evaluation [TS86, War92] and constraint logic programming [JM94] is described (TCLP). This combination has been studied previously from a theoretical point of view [Tom97, Cod95], where it is shown that the constraint domain needs to offer projection and entailment checking operations in order to ensure completeness w.r.t. the declarative semantics. However, existing TCLP frameworks and implementations lack a complete treatment of constraint projection and / or entailment. The novelty of our proposal is that we present a complete implementation framework for TCLP, independent from the constraint solver, which can use either precise or approximate projection and entailment, possibly with optimizations.
