Weba good idea to use the minimax algorithm? Answer: The outcome of MAX can only be the same or better if MIN plays suboptimally compared to MIN playing optimally. So, in general, it seems like a good idea to use minimax. However, suppose MAX assumes MIN plays optimally and minimax determines that MIN will win. In such cases, all moves are losing … Webαβ-search = minimax search with αβ pruning. α: value, best p1 option so far, on path current-to-root. β: value, best p2 option so far, on path current-to-root. minimax, so can be used as a solver. leaf scores must be true scores. must be able to reach all leaf nodes in reasonable time. can also be used as heuristic player
