测量大型无限制扑克游戏的大小

Measuring the Size of Large No-Limit Poker Games

Michael Johanson

摘要:

在计算博弈论领域,博弈经常以其规模进行比较。这可以通过几种方式来衡量,包括唯一游戏状态的数量,决策点的数量,以及所有决策点上的法律行为的总数。这些数字要么是已知的,要么是对国际象棋和跳棋等各种经典游戏的估计。在随机和不完全信息的扑克游戏中,这些大小很容易在限制玩家可用行动的“限制”游戏中计算,但到目前为止,只有更复杂的“无限制”变体才能估计。在本文中,我们描述了一个简单的算法来快速计算两个人的无限制扑克游戏的大小,提供了该算法的实现,并提出了第一次精确计数的游戏状态,信息集,行动和终端节点的数量在年度计算机扑克比赛中玩的无限制扑克游戏。

英文摘要:

In the field of computational game theory, games are often compared in terms of their size. This can be measured in several ways, including the number of unique game states, the number of decision points, and the total number of legal actions over all decision points. These numbers are either known or estimated for a wide range of classic games such as chess and checkers. In the stochastic and imperfect information game of poker, these sizes are easily computed in "limit" games which restrict the players' available actions, but until now had only been estimated for the more complicated "no-limit" variants. In this paper, we describe a simple algorithm for quickly computing the size of two-player no-limit poker games, provide an implementation of this algorithm, and present for the first time precise counts of the number of game states, information sets, actions and terminal nodes in the no-limit poker games played in the Annual Computer Poker Competition.
