Interface SolutionChecker

All Superinterfaces:

GoalTest

public interface SolutionChecker
extends GoalTest

A specialization of the GoalTest interface so that it is possible to check the solution once a goal has been identified to determine if it is acceptable. This allows you to continue searching for alternative solutions without having to restart the search.

However, care needs to be taken when doing this as it does not always make sense to continue with a search once an initial goal is found, for example if using a heuristic targeted at a single goal.
