What is Unification and Backtracking in Prolog about?
Prolog uses unification and backtracking to evaluate goals. Unification matches predicates to make them identical and bind variables, while backtracking allows Prolog to search through facts and rules to find solutions. The document provides examples demonstrating unification, backtracking, and recursion in Prolog programs for queries like finding ancestors and factorials. It defines a goal to print countries with a population over 10 million using facts for country populations.
