On von neumann's minimax theorem

WebOur proofs rely on two innovations over the classical approach of using Von Neumann’s minimax theorem or linear programming duality. First, we use Sion’s minimax theorem to prove a minimax theorem for ratios of bilinear functions representing the cost and score of … WebIn our companion manuscript [BB20], we use one of the query versions of our minimax theorem (Theorem 4.6) to prove a new composition theorem for randomized query complexity. 1.2 Main tools Minimax theorem for cost/score ratios. The first main result is a new minimax theorem for the ratio of the cost and score of randomized algorithms.

A Robust von Neumann Minimax Theorem for Zero-Sum Games …

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 WebVon Neumann proved the minimax theorem (existence of a saddle-point solution to 2 person, zero sum games) in 1928.
