Robotics & Artificial Intelligence- Prolog Codes

Prolog is a logical and a declarative programming language. The name itself, Prolog, is short for PROgramming in LOGic. Prolog's heritage includes the research on theorem provers and other automated deduction systems developed in the 1960s and 1970s. The inference mechanism of Prolog is based upon Robinson's resolution principle (1965) together with mechanisms for extracting answers proposed by Green (1968). These ideas came together forcefully with the advent of linear resolution procedures. Explicit goal-directed linear resolution procedures, such as those of Kowalski and Kuehner (1971) and Kowalski (1974), gave impetus to the development of a general purpose logic programming system. The "first" Prolog was "Marseille Prolog" based on work by Colmerauer (1970). The first detailed description of the Prolog language was the manual for the Marseille Prolog interpreter (Roussel, 1975). The other major influence on the nature of this first Prolog was that it was designed to facilitate natural language processing.
Prolog is the major example of a fourth generation programming language supporting the declarative programming paradigm. The Japanese Fifth-Generation Computer Project, announced in 1981, adopted Prolog as a development language, and thereby focused considerable attention on the language and its capabilities. The programs in this tutorial are written in "standard" (University of) Edinburgh Prolog, as specified in the classic Prolog textbook by authors Clocksin and Mellish (1981,1992). The other major kind of Prolog is the PrologII family of Prologs which are the descendants of Marseille Prolog. The reference to Giannesini, (1986) uses a version of PrologII. There are differences between these two varieties of Prolog; part of the difference is syntax, and part is semantics. However, students who learn either kind of Prolog can easily adapt to the other kind.
