COMP30024 Artificial Intelligence Week 5 Problem Sheet Weekly Topic Review In adversarial search, two players, MAX and MIN, compete in zero-sum, perfect information games. Both players want to find a sequence of actions leading to a win, contingent on the strategy of their opponent. What strategy is reasonable? The minimax algorithm develops a strategy assuming […]
