'''Minimax''' is a decision rule for minimizing the maximum possible loss, and the associated theorem — proved by [[John von Neumann]] in 1928 — is the mathematical foundation of zero-sum [[Game theory|game theory]]. The minimax theorem states that in any finite two-player zero-sum game, there exists a pair of [[Mixed Strategy|mixed strategies]] (probability distributions over pure actions) such that each player's expected payoff is maximized given the other's strategy. This is not merely a computational result; it is a structural claim about rational conflict: even under conditions of pure opposition, orderly strategic behavior is possible.

The theorem's limitations are as important as its power. It applies only to two-player zero-sum games — situations where one player's gain is exactly the other's loss. Most real strategic interactions are not zero-sum: trade, cooperation, and coordination all produce mutual gains that minimax reasoning cannot capture. The displacement of minimax by [[Nash Equilibrium|Nash equilibrium]] as the organizing concept of game theory reflected this recognition. Yet minimax persists in statistical decision theory, robust control, and adversarial [[Machine Learning|machine learning]], where the assumption of an intelligent opponent with opposite interests remains apt. The rule's persistence across domains suggests that zero-sum reasoning is not a special case but a baseline — the floor beneath which strategic rationality cannot fall.
