On von neumann's minimax theorem
WebIn mathematics, von Neumann's theorem is a result in the operator theory of linear operators on Hilbert spaces.. Statement of the theorem. Let and be Hilbert spaces, and let : be an unbounded operator from into . Suppose that is a closed operator and that is densely defined, that is, is dense in . Let : denote the adjoint of . Then is also … WebThe theorem was first proved by the Hungarian-born US mathematician John von Neumann (1903–57) and published in the journal Mathematische Annalen in 1928.

WebThe Minimax algorithm is the most well-known strategy of play of two-player, zero-sum games. The minimax theorem was proven by John von Neumann in 1928. Minimax is a strategy of always minimizing the maximum possible loss which can result from a choice that a player makes. 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-sum games.
