WebThe maximin-minimax principle is used for the selection of optimal strategies by two players. This method is also known as a calculus method. The Minimax Theorem For every finite two-person zero-sum game, there is a number v, called the value of the game WebThis is minimax-optimal (up to log factor) when m m is fixed. When applied to two-player zero-sum Markov games, our algorithm provably finds an ε ε -approximate Nash equilibrium with a minimal number of samples. Along the way, we derive a refined regret bound for FTRL that makes explicit the role of variance-type quantities, which might be of ...
