On von neumann's minimax theorem

In the mathematical area of game theory, a minimax theorem is a theorem providing conditions that guarantee that the max–min inequality is also an equality. The first theorem in this sense is von Neumann's minimax theorem about zero-sum games published in 1928, which was considered the starting point of … Ver mais The theorem holds in particular if $${\displaystyle f(x,y)}$$ is a linear function in both of its arguments (and therefore is bilinear) since a linear function is both concave and convex. Thus, if Ver mais • Sion's minimax theorem • Parthasarathy's theorem — a generalization of Von Neumann's minimax theorem • Dual linear program can be used to prove the minimax theorem for zero … Ver mais WebJohn von Neumann [1928a] stated the minimax theorem for two-person zero-sum games with finite numbers of pure strategies and constructed the first valid proof of the theorem, using a topological approach based on Brouwer's fixed point theorem. He noted in his paper that his theorem and proof solved a problem posed by Borel, to whom he sent a ...

WebON GENERAL MINIMAX THEOREMS MAURICE SION 1. Introduction, von Neumann's minimax theorem [10] can be stated as follows : if M and N are finite dimensional simplices and / is a bilinear function on MxN, then / has a saddle point, i. e. max min f(μ, v) = min max f(μ, v) .
