Prolog in a sentence

Graphics Prolog systems that provide a graphics library are SWI-prolog, citation Visual-prolog, LPA Prolog for Windows and B-Prolog.

As a result, many practical Prolog programs are written to conform to Prolog's depth-first search order, rather than as purely declarative logic programs.

As Turbo Prolog, it was marketed by Borland, but it is now developed and marketed by the Danish firm PDC (Prolog Development Center) that originally produced it.

However, not all Prolog compilers support modules, and there are compatibility problems between the module systems of the major Prolog compilers.

Limitations Although Prolog is widely used in research and education, Prolog and other logic programming languages have not had a significant impact on the computer industry in general.

Programming in Prolog In Prolog, loading code is referred to as consulting.

Prolog is based on the idea of Artificial Intelligence.

A library that can be used standalone or within Symfony2.1 framework History The name Prolog was chosen by Philippe Roussel as an abbreviation for programmation en logique main ( French for programming in logic ).

Allows the development of GUIs and other functionality in Java while leaving logic processing in the Prolog layer.

An equivalent operator is normally built-in in modern Prolog 's implementations.

By 1988 Erlang had proven that it was suitable for prototyping telephone exchanges, but the Prolog interpreter was far too slow.

Consider for example if negation were included in the following Prolog program: : not Q. : Q :- P. The above program would be unable to prove not P even though it follows by the rules of mathematical logic.

Data types Prolog's single data type is the term. Terms are either atoms, numbers, variables or compound terms.

Due to the use of information obtained at compile time (such as type and mode information), programs written in Mercury typically perform significantly faster than equivalent programs written in Prolog.

Extensions Various implementations have been developed from Prolog to extend logic programming capabilities in numerous directions.

For this reason, a comparatively small set of library predicates suffices for many Prolog programs.

Given a query, the Prolog engine attempts to find a resolution refutation of the negated query.

Highly portable, it supports most standard-complaint Prolog systems as backend compilers.

In particular, Prolog's non-deterministic evaluation strategy can be problematic when programming deterministic computations, or when even using "don't care non-determinism" (where a single choice is made instead of backtracking over all possibilities).

In Prolog, design patterns go under various names: skeletons and techniques, citation citation cliches, D. Barker-Plummer.
