Minimax theorem 中文
Webory on minimax approximation is treated in these books as well. The main idea behind the Remez algorithm is based on the alternation the-orem, to which section 4 is devoted. The alternation theorem provides us with a method to directly calculate the best minimax approximation on a reference, which is a discrete subset of [a;b].

WebMINIMAX THEOREM I Assume that: (1) X and Z are convex. (2) p(0) = inf x∈X sup z∈Z φ(x,z) < ∞. (3) Foreachz ∈ Z,thefunctionφ(·,z)isconvex. (4) For each x ∈ X, the function −φ(x,·):Z → is closed and convex. Then, the minimax equality holds if and only if the function p is lower semicontinuous at u =0. Proof: Theconvexity ... WebVon Neumann’s minimax theorem, widely considered the rst key result in game theory, tells us that both the Player and the Adversary have an \optimal" randomized strategy that can be played without knowledge of the strategy of their respective opponent.
