5 HEURISTIC FUNCTIONS In Section 2 . 1 . 2 , a heuristic was defined as a
technique that aids in the discovery of solutions to problems even though there is
no guarantee that it will never lead in the wrong direction . It was pointed out that

In a pure generate and test procedure , the test function responds with only a yes
or no . But if the test function is augmented with a heuristic function that provides
an estimate of how close a given state is to a goal state , the generate procedure

This is done using a static evaluation function , which uses whatever information
it has to evaluate individual board positions by estimating how likely they are to
lead eventually to a win . Its function is similar to that of the heuristic function h ' in
