On two minimax theorems in graph - ScienceDirect
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 … Visa mer 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 Visa mer • 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 … Visa mer Webb24 mars 2024 · The fundamental theorem of game theory which states that every finite, zero-sum, two-person game has optimal mixed strategies. It was proved by John von Neumann in 1928. Formally, let X and Y be mixed strategies for players A and B. Let A be the payoff matrix. Then max_(X)min_(Y)X^(T)AY=min_(Y)max_(X)X^(T)AY=v, where v is … john stein facebook
