Question
Explain the Minimax algorithm with an example.
Answer
The Minimax algorithm is a decision-making strategy in two-player zero-sum games where players try to maximize their score while minimizing the opponent's.
The Minimax algorithm is a recursive or backtracking algorithm used in decision-making and game theory. It provides an optimal move for a player assuming that the opponent is also playing optimally. The algorithm constructs a game tree where nodes represent game states.
In a two-player zero-sum game, one player is the 'Maximizer' trying to get the highest possible score, and the other is the 'Minimizer' trying to get the lowest score. For example, in a game of Tic-Tac-Toe, if X is the Maximizer, X will choose the move that leads to the highest evaluated terminal node (+1 for win), assuming O will always choose the move that leads to the lowest evaluated node (-1 for X loss).
