Prolog
(programming)Programming in Logic or (French) Programmation
en Logique. The first of the huge family of logic programming languages.
Prolog was invented by Alain Colmerauer and Phillipe Roussel at the University of Aix-Marseille in 1971. It was first implemented 1972 in ALGOL-W. It was designed originally for natural-language processing but has become one of the most widely used languages for artificial intelligence.
It is based on LUSH (or SLD) resolution theorem proving and unification. The first versions had no user-defined functions and no control structure other than the built-in depth-first search with backtracking. Early collaboration between Marseille and Robert Kowalski at University of Edinburgh continued until about 1975.
Early implementations included C-Prolog, ESLPDPRO, Frolic, LM-Prolog, Open Prolog, SB-Prolog, UPMAIL Tricia Prolog. In 1998, the most common Prologs in use are Quintus Prolog, SICSTUS Prolog, LPA Prolog, SWI Prolog, AMZI Prolog, SNI Prolog.
ISO draft standard at Darmstadt, Germany. or UGA, USA.
See also negation by failure, Kamin's interpreters, Paradigms of AI Programming, Aditi.
A Prolog interpreter in Scheme. ftp://cpsc.ucalgary.ca/pub/prolog1.1.
A Prolog package from the University of Calgary features delayed goals and interval arithmetic. It requires Scheme with continuations.

Prolog
(PROgramming in LOGic) A programming language used for developing AI applications (natural language translation, expert systems, abstract problem solving, etc.). Developed in France in 1973, "Programmation en Logique" is used throughout Europe and Japan and has gained popularity in the U.S.Similar to LISP, it deals with symbolic representations of objects. The following example, written in University of Edinburgh Prolog, converts Fahrenheit to Celsius:
convert:- write('Enter Fahrenheit'),
read(Fahr),
write('Celsius is '),
Cent is (5 * (Fahr - 32)) / 9,
write(Cent),nl.
