Heuristic Algorithm

UPDATE: 03/2010 - after too many time, I remember this Algorithm, I'm uploading a new version for VB.NET 2005 - Regards :D This form use the Heuristic Algorithm to find the objetive puted by the user randomly, this is a method used in IA to Vision Recognize. click the first time in the white area to put de start position, click again to put the objetive position, and then put wherever you want to put the obstacles to avoid, then click in go button, if you put so many, the algorithm takes 2 - 3 minutes to finish the search
