摘要
我们考虑的是具有随机回报的有限双人正则表达式博弈。玩家 A 的收益是均匀分布的 i.i.d.。给定 p∈[0,1],对于任何行动轮廓,棋手 B 的收益与棋手 A 的收益重合的概率为 p,并且是来自同一均匀分布的 i.i.d.,概率为 1-p。这个模型插值了大多数文献中使用的 i.i.d. 随机报酬模型和随机潜在博弈模型。首先,我们研究上述博弈中纯纳什均衡的数量。然后,我们证明,对于任意正 p,在可用行动的数量上,渐近地,最佳响应动力学以很高的概率达到纯纳什均衡。
Best-response dynamics in two-person random games with correlated payoffs
We consider finite two-player normal form games with random payoffs. Player A's payoffs are i.i.d. from a uniform distribution. Given , for any action profile, player B's payoff coincides with player A's payoff with probability p and is i.i.d. from the same uniform distribution with probability . This model interpolates the model of i.i.d. random payoff used in most of the literature and the model of random potential games. First we study the number of pure Nash equilibria in the above class of games. Then we show that, for any positive p, asymptotically in the number of available actions, best response dynamics reaches a pure Nash equilibrium with high probability.
