heuristic

public double heuristic(GamePlay game,
                        GameMove move,
                        int[] role)

this heuristic is basically counting pieces, but as long as the game is not over, it weights the pieces differently according to their potential for a final win. Following this strategy, corner tiles (as they're not alterable anymore) are rated the highest, and border pieces are also rated higher than others.

Parameters:

game - DOCUMENT ME!

move - DOCUMENT ME!

role - DOCUMENT ME!

Returns:

DOCUMENT ME!
