建立合作网络

Building Cooperative Networks

Ignacio Gomez Portillo

摘要:

我们在演化博弈论的框架下研究合作问题,并以囚徒困境作为问题的隐喻。考虑到系统和个人的模仿能力的增长过程中,我们显示的条件,允许形成任何规模和拓扑结构的高度合作的网络。引入真实系统的一般考虑,我们减少了合作所需的条件,以接近收益成本比r理论上的最小值r=1,当个人的平均连通性增加。通过本文,我们区分了不同的机制,使系统保持高水平的合作时,系统的增长,纳入叛逃者。这些机制需要个体之间的异质性,以促进合作的发展。然而,所需的条件和异质性大大减少相比,静态网络所需的。

英文摘要:

We study the cooperation problem in the framework of evolutionary game theory using the prisoner's dilemma as metaphor of the problem. Considering the growing process of the system and individuals with imitation capacity, we show conditions that allow to form highly cooperative networks of any size and topology. Introducing general considerations of real systems, we reduce the required conditions for cooperation to evolve approaching the benefit-cost ratio r to the theoretical minimum r=1, when the mean connectivity of the individuals is increased. Through the paper, we distinguish different mechanisms that allow the system to maintain high levels of cooperation when the system grows by incorporation of defectors. These mechanisms require heterogeneity among individuals for cooperation to evolve. However, the required conditions and heterogeneities are drastically reduced as compared to those required for static networks.
