利用强同构构造对策策略空间

Using strong isomorphisms to construct game strategy spaces

Michael J. Gagen

摘要:

当应用于同一个博弈时,概率论和博弈论可能在费雪信息、对数似然函数、熵梯度、变量变换的秩和雅可比矩阵,甚至潜在概率参数空间的维数和体积的计算值上存在分歧。这些差异的出现是因为概率论在构造策略空间来分析博弈时采用了保结构同构映射。相比之下,博弈论使用较弱的映射,它改变了混合策略空间内潜在概率分布的一些属性。在本文中,我们将探讨如何使用强同构映射来定义博弈策略空间,可以改变简单博弈中的理性结果,并可能解决一些博弈论的悖论。

英文摘要:

When applied to the same game, probability theory and game theory can disagree on calculated values of the Fisher information, the log likelihood function, entropy gradients, the rank and Jacobian of variable transforms, and even the dimensionality and volume of the underlying probability parameter spaces. These differences arise as probability theory employs structure preserving isomorphic mappings when constructing strategy spaces to analyze games. In contrast, game theory uses weaker mappings which change some of the properties of the underlying probability distributions within the mixed strategy space. In this paper, we explore how using strong isomorphic mappings to define game strategy spaces can alter rational outcomes in simple games, and might resolve some of the paradoxes of game theory.
