信念、协调博弈与均衡选择

非合作博弈理论能够很好解决处于竞争关系参与人之间合作与冲突,但在处理严格纳什均衡之间的选择时,碰到难以逾越的鸿沟。于是,均衡选择问题变成了博弈论理论家们研究的热点,协调博弈成为继囚徒困境博弈又一被广泛研究的博弈类型。已有的均衡研究法没有把系统达到均衡的过程引入到模型当中,无法考虑参与人关于博弈历史而形成有关对手未来行动的信念对均衡选择的影响,难以现实地考察均衡演化。本文基于协调博弈动态过程研究的基础上,通过引入历史、现状及相对偏好参数来探讨协调博弈的均衡选择问题,为理论研究提供一种新思路。

Belief, Coordination Game and Equilibrium Selection

Non-cooperation game theory can effectively deal with the cooperation and conflicts among competitors.But it encountered insurmountable barrier when face selection of strict Nash equilibrium.Therefore,equilibrium selection became a hot topic to game theory theorists,coordination game became another type of extensive research Game after Prisoner's Dilemma game.The previous equilibrium study did not introduce the process of achieving system equilibrium into the model to consider the belief affection for equilibrium selection referring to the history of game,and made it hard to inspect equilibrium evolution realistically.This article is based on the dynamic process research of coordination game,through introducing the history,current status and relative preference parameters to explore equilibrium options to coordination game,in order to provide a new idea to theoretical study.
