The Answer is The search will repeatedly move the 2,3,and 4 tiles around in the bottom right corner because doing otherwise would cause an additional tile to be moved out of its correct position.A solution is to rate the various options by the sum of the heuristic value and the number of moves required to reach the current position rather than merely the heuristic.This allows moves that increase the heuristic to ultimately look better than continuing to repeat moves that do not increase the heuristic.
