A robot placed at the "Start" position is being programmed navigate the below maze to reach the nearest exit marked by numbers (in black color) which represents the prize money obtainable at the end of the scarch. The goal state expected is to get atleast 4 as the prize amount. Each of the Exit point and the intersections of the maze marked in blue represents the decision nodes for the robot to process its move, with the latter has stored heuristic value to reach the goal marked in square bracket.
