Abstract

Although most studies in the field of game-driven population dynamics are concentrated on imitation update rule, it is the logit update rule that is dominated in many cases in society. Despite the fact that it may seem to be an intelligence method to choose the most profitable strategy, it often can lead to a lower level of cooperation in society. This study aims at investigating the effect of using an extra source of information in the process of each strategy profitability estimation. Our simulation shows that making decisions based on these new sources of information can improve the logit update rule and make cooperators more resistant against defection. Moreover, increasing information gathering area and memory power as much as possible does not necessarily in the favor of cooperation level in society. instead, maximum average cooperation level occurs in moderate values of vision range and memory damping coefficient. Effective probable mechanisms in happening such a phenomenon are also discussed.

记忆力和视野范围对捐赠游戏中合作者动态的影响

摘要

尽管大多数游戏驱动的人口动力学领域的研究都集中在模仿更新规则上，但在社会上的许多情况下，对数更新规则却是占主导地位的。尽管事实似乎是选择最有利可图的策略的明智方法，但它通常会导致社会合作水平降低。本研究旨在调查在每个策略获利能力估计过程中使用额外信息源的影响。我们的仿真表明，基于这些新的信息源做出决策可以改善logit更新规则，并使合作者更能抵御叛逃。而且，尽可能增加信息收集面积和存储能力并不一定有利于社会中的合作水平。反而，最大的平均合作水平出现在适度的视觉范围和记忆阻尼系数中。还讨论了发生这种现象的有效可能机制。
