This chapter describes SWI-Prolog's support for Tabled execution for one or more Prolog predicates, also called SLG resolution.Tabling a predicate provides two properties: Re-evaluation of a tabled predicate is avoided by memoizing the answers. This can realise huge performance enhancements as illustrated in section 7.1.
