Q1.(10)
Write a state space solution for following problem. Write clearly; What are Initial State, Final State, Rules, control strategy for this problem. Write generalized set of rules for the same. Can you indicate a heuristic for solving the problem faster?
A hungry monkey finds himself in a room where a bunch of bananas is hanging from the ceiling. The monkey, can not reach the bananas directly. The ceiling is the just the right height that monkey standing on a chair, weaving stick can knock the bananas down. The monkey knows how to move around, carry other things around, reach for the bananas, and wave a stick in the air. Get the rules to solve the problem and help the monkey out.
