Dynamical reciprocity in interacting games: numerical results and mechanism analysis

摘要:

我们研究了两个相互作用的博弈的演化,既有成对博弈,也有不同拓扑结构上的公共产品博弈。在二维正方形格子上,我们发现博弈-博弈的相互作用在所有情况下都能促进合作的普遍性,当相互作用变得很强时,合作-背叛的相变甚至消失,并且期望有相当高的合作。一个平均场论的发展,指出新的动力学路线中产生的。详细的分析表明,无论是个人还是群体的情况下,确实有丰富的相互作用的类别:入侵,中性,催化类型;它们的组合使合作者在一个持久的优势地位,这促进了合作。揭示的互惠性的鲁棒性通过对模型变量的研究而得到加强,包括不对称或时变相互作用、不同类型的博弈、具有时标分离的博弈、不同更新规则等。底层种群的结构复杂性,如Newman-Watts小世界网络、Erdens-Rényi随机网络和Barabási-Albert网络,也不改变动力学互易性的工作。特别地,随着参与的游戏数量的增加,合作水平总体上持续提高。因此,我们的工作揭示了一类新的合作机制,并指出了人类合作的巨大潜力,在现实世界中经常看到并发的问题。

英文摘要:

We study the evolution of two mutually interacting games with both pairwise games as well as the public goods game on different topologies. On 2d square lattices, we reveal that the game-game interaction can promote the cooperation prevalence in all cases, and the cooperation-defection phase transitions even become absent and fairly high cooperation is expected when the interaction goes to be very strong. A mean-field theory is developed that points out new dynamical routes arising therein. Detailed analysis shows indeed that there are rich categories of interactions in either individual or bulk scenario: invasion, neutral, and catalyzed types; their combination puts cooperators at a persistent advantage position, which boosts the cooperation. The robustness of the revealed reciprocity is strengthened by the studies of model variants, including asymmetrical or time-varying interactions, games of different types, games with time-scale separation, different updating rules etc. The structural complexities of the underlying population, such as Newman--Watts small world networks, Erdős--Rényi random networks, and Barabási--Albert networks, also do not alter the working of the dynamical reciprocity. In particular, as the number of games engaged increases, the cooperation level continuously improves in general. Our work thus uncovers a new class of cooperation mechanism and indicates the great potential for human cooperation where concurrent issues are so often seen in the real world.
