Query: Enhancing a Search Algorithm to Perform Intelligent Backtracking   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.
