PROGRAMMING PEARL: Enhancing a search algorithm to perform intelligent backtracking
Published online by Cambridge University Press: 16 April 2004
Abstract
This paper illustrates how a Prolog program, using chronological backtracking to find a solution in some search space, can be enhanced to perform intelligent backtracking. The enhancement crucially relies on the impurity of Prolog that allows a program to store information when a dead end is reached. To illustrate the technique, a simple search program is enhanced.
