@Deprecated
public interface AStarHeuristic<NODE>

This is an interface containing a method for computing the AStar heuristic. That means the estimation how far the goal is from some node that is currently being visited by AStar.

Method Summary

int	getEstimatedDistanceToGoal(NODE node) Deprecated. This is heuristic function.

Method Detail

getEstimatedDistanceToGoal

int getEstimatedDistanceToGoal(NODE node)

Deprecated.

This is heuristic function.

WARNING:

This heuristic must be correct for A* to work correctly, that means the returned distance must be smaller or equal to the real distance and must be monotonic. (In 2D, 3D an euclidean metric will do the job).

Returns:

how far is to the goal from the node
