Chapter 11.3, Problem 6QE

Program Plan Intro

Heuristic system:

The heuristic system considers all the immediate possible conditions that may lead to a solution for the problem. The system proceeds in the same manner until all the possible conditions are achieved. The heuristic system may require a large amount of work, but ultimately it approaches towards a solution. The solution is one of the conditions achieved at the last. The conditions achieved at last may be in a large number. It guarantees to have a solution among many conditions achieved in the end.
