论文摘要

下议院的悲剧(TOC)是一种无处不在的社会难题,在一个可用的生命实体和共享资源之间的相互作用中见证了:人口中的个人往往会自私地过度剥化一种共同的资源,因为它是合理的选择,或者在非人类众生的情况下,它可能是进化的不可思议的行动。如何避免TOC是与资源保护有关的一个重大问题。不难设想资源可以自我更新,人口的规模可能取决于使用不同剥削率的人口的分数取决于资源的状态。如果资源的自我更新率位于最大剥削率和最低剥削率之间,那么在避免TOC的哪些条件下,这并不是先验的。在本文中,我们使用进化游戏理论复制器方程的设置在分析和数字上解决了这个问题,该方程将自然选择的达尔文宗旨建模。通过复制器方程式,当我们研究复制器的人群如何利用共享资源时,后者对前者的动态反馈也不容忽视。我们还提出了游戏资源反馈模型的透明自下而上推导,以促进对本文提出的发现的随机影响的未来研究。

The tragedy of the commons (TOC) is a ubiquitous social dilemma witnessed in interactions between a population of living entities and shared resources available to them: The individuals in the population tend to selfishly overexploit a common resource as it is arguably the rational choice, or in case of non-human beings, it may be an evolutionarily uninvadable action. How to avert the TOC is a significant problem related to the conservation of resources. It is not hard to envisage situations where the resource could be self-renewing and the size of the population may be dependent on the state of the resource through the fractions of the population employing different exploitation rates. If the self-renewal rate of the resource lies between the maximum and the minimum exploitation rates, it is not a priori obvious under what conditions the TOC can be averted. In this paper, we address this question analytically and numerically using the setup of an evolutionary game theoretical replicator equation that models the Darwinian tenet of natural selection. Through the replicator equation, while we investigate how a population of replicators exploit the shared resource, the latter's dynamical feedback on the former is also not ignored. We also present a transparent bottom-up derivation of the game-resource feedback model to facilitate future studies on the stochastic effects on the findings presented herein.
