Minimax theorem 中文

Web1 mrt. 1994 · Abstract. This paper offers an alternative proof of the so-called fundamental theorem of the theory of games or the minimax theorem. The proof uses a particularization of Farkas' theorem involving the expression of one vector as a convex combination of a set of vectors. It is demonstrated that the minimax theorem holds as a … WebDevoted to minimax theorems and their applications to partial differential equations, this text presents these theorems in a simple and unified way, starting from a quantitative deformation lemma. Many applications are given to problems dealing with lack of compactness, especially problems with critical exponents and existence of solitary waves.

WebThe Minimax Theorem Recall: A zero-sum game is a two-player game with u i(a)+ u i(a) = 0. Theorem 2 (Von Neumann, 1928) In azero-sum game, a strategy pro le is aNEi each player’s expected utility equals herminimax value. Proof: Let v i be the minimax/maximin value of player i (and v i = v i that of player i). (1) Suppose u i(s i;s i) 6= v i.
