WebHere we will see one Prolog program, that can find the minimum of two numbers and the maximum of two numbers. First, we will create two predicates, find_max (X,Y,Max). This takes X and Y values, and stores the maximum value into the Max. Similarly find_min (X,Y,Min) takes X and Y values, and store the minimum value into the Min variable. Program

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.
