For example, consider the following program to find the max element between 2 numbers: max_element (X, Y, X) :- X > Y. % If X > Y, then X is the max element max_element (X, Y, Y) :- X =< Y. % If X <= Y, then Y is the max element
WebProlog is very good at pattern matching and search. Two features in a programming language that make pattern- matching easier are 1) support for symbols as a primitive data type that can be manipulated without the need to call special functions, and 2) dynamic memory management WebAnd as we said in the previous chapter: matching is one of the fundamental ideas in Prolog. Here's a more precise definition for matching which not only tells us when two terms …
WebMay 2, 1997 · Among the features of Prolog are `logical variables' meaning that they behave like mathematical variables, a powerful pattern-matching facility (unification), a backtracking strategy to search for proofs, uniform data structures, and input and output are interchangeable.
WebProlog is declarative: A program is a collection of ‘axioms’ from which ‘theorems’ can be proven.
