不完全信息博弈的分解求解

Solving Imperfect Information Games Using Decomposition

Neil Burch, Michael Johanson, Michael Bowling

摘要:

分解,即独立分析可能的子博弈,已被证明是完美信息博弈中有效决策的基本原则。然而,在不完全信息博弈中,分解被证明是有问题的。到目前为止,所有提出的技术在不完全信息博弈的分解已经放弃了理论保证。这项工作提出了第一种技术,用于将不完美信息博弈分解为可以独立求解的子博弈,同时保留对全博弈解的最优性保证。我们可以使用这种技术来构建理论上合理的算法,这些算法可以更好地利用运行时可用的信息,克服运行时的内存或磁盘限制,或者在解决游戏时进行时间/空间权衡以克服内存或磁盘限制。特别是,我们提出了一个算法,保证在整个游戏的性能,在现有的方法,可能有无限的错误。此外,我们提出了一个离线游戏求解算法,CFR-D,它可以产生一个纳什均衡的游戏,是大于可用存储。

英文摘要:

Decomposition, i.e. independently analyzing possible subgames, has proven to be an essential principle for effective decision-making in perfect information games. However, in imperfect information games, decomposition has proven to be problematic. To date, all proposed techniques for decomposition in imperfect information games have abandoned theoretical guarantees. This work presents the first technique for decomposing an imperfect information game into subgames that can be solved independently, while retaining optimality guarantees on the full-game solution. We can use this technique to construct theoretically justified algorithms that make better use of information available at run-time, overcome memory or disk limitations at run-time, or make a time/space trade-off to overcome memory or disk limitations while solving a game. In particular, we present an algorithm for subgame solving which guarantees performance in the whole game, in contrast to existing methods which may have unbounded error. In addition, we present an offline game solving algorithm, CFR-D, which can produce a Nash equilibrium for a game that is larger than available storage.
