Class AdaptableHeuristicFunction

java.lang.Object
  aima.search.map.AdaptableHeuristicFunction

All Implemented Interfaces:

HeuristicFunction, java.lang.Cloneable

public abstract class AdaptableHeuristicFunction
extends java.lang.Object
implements HeuristicFunction, java.lang.Cloneable

This class extends heuristic functions in two ways: It maintains a goal and a map to estimate distance to goal for states in route planning problems, and it provides a method to adapt to different goals.

Field Summary

protected java.lang.Object	goal The Current Goal.
protected Map	map The map to be used for distance to goal estimates.

Method Detail

getAdaptation

public AdaptableHeuristicFunction getAdaptation(java.lang.Object goal,
                                                Map map)

Creates a clone and stores goal and map in the corresponding attributes. This method MUST be called before using the heuristic!
