6.13 What is the performance score that one could expect from the optimal wumpus world agent? Design an experiment wherein you look at all possible 4 x 4 wumpus worlds (or a random sample of them if there are too many), and for each one determine the shortest safe path to pick up the gold and return to start, and thus the best score. This gives you an idea of the expected performance score for an ideal omniscient agent. How could you determine the expected score for an optimal non-omniscient agent?
