通过本地化的小世界通信促进合作

Promote cooperation by localised small-world communication

摘要:

在相当大的不相关人群中,合作的出现和维持给我们的理解带来了许多挑战。我们认为,人类的沟通能力,如有多少和多远的同胞可以建立相互沟通,可能会影响合作的演变。我们研究这个问题的公共物品游戏(PGG)的两层网络的联系。参与者从正方形格子(交互层)上的五人公共物品交互中获得收益。此外,他们在学习层与邻居沟通后更新策略,其中两个参与者根据他们的空间距离以幂律概率建立相互沟通。我们的模拟结果表明,合作的演变确实是敏感的球员如何选择他人进行通信,包括金额以及位置。地方化交流趋势被证明是促进合作的新机制。

英文摘要:

The emergence and maintenance of cooperation within sizable groups of unrelated humans offer many challenges for our understanding. We propose that the humans' capacity of communication, such as how many and how far away the fellows can build up mutual communications, may affect the evolution of cooperation. We study this issue by means of the public goods game (PGG) with a two-layered network of contacts. Players obtain payoffs from five-person public goods interactions on a square lattice (the interaction layer). Also, they update strategies after communicating with neighbours in learning layer, where two players build up mutual communication with a power law probability depending on their spatial distance. Our simulation results indicate that the evolution of cooperation is indeed sensitive to how players choose others to communicate with, including the amount as well as the locations. The tendency of localised communication is proved to be a new mechanism to promote cooperation.
