繁殖时间尺度的多样性促进空间囚徒困境博弈中的合作

Diversity of reproduction time scale promotes cooperation in spatial prisoner's dilemma games

Zhi-Xi Wu, Zhihai Rong, Petter Holme

摘要:

我们研究了一个进化的空间囚徒困境游戏,其中的球员的健身是由当前的互动和他们的历史的回报。我们考虑的情况下,选择的时间尺度是慢于互动的时间尺度。这是通过在个体水平上实现概率再现来完成的。我们注意到,繁殖速度过快和过慢都会阻碍合作的出现。换句话说,存在一个中间选择时间尺度,使合作最大化。我们发现促进合作的另一个因素是繁殖时间尺度的多样性。

英文摘要:

We study an evolutionary spatial prisoner's dilemma game where the fitness of the players is determined by both the payoffs from the current interaction and their history. We consider the situation where the selection timescale is slower than the interaction timescale. This is done by implementing probabilistic reproduction on an individual level. We observe that both too fast and too slow reproduction rates hamper the emergence of cooperation. In other words, there exists an intermediate selection timescale that maximizes cooperation. Another factor we find to promote cooperation is a diversity of reproduction timescales.
