拓扑依赖的收益可以导致从囚徒困境中逃脱

Topology dependent payoffs can lead to escape from prisoner's dilemma

Saptarshi Sinha, Deep Nath, Soumen Roy

摘要:

在存在空间限制的情况下,合作的维持已经得到了广泛的研究。众所周知,底层图拓扑结构可以显著影响图上游戏的结果。保持合作可能很困难,特别是在没有空间限制的情况下。合作的演变自然取决于收益。然而,在给定的博弈中,收益通常被认为是不变的。一个自然但尚未探索的问题是,游戏所处的底层结构的拓扑结构是否在决定收益方面没有任何作用。在这里,我们引入了合作图和背叛图的概念,以及一种新形式的游戏支付,这是弱依赖于底层网络拓扑结构。这些概念的灵感来自于众所周知的微生物群体感应现象。我们证明,即使有这样一个弱的依赖,基本的游戏动态,甚至游戏的性质可能会改变。这种游戏性质的变化在理论和实验研究中都有很好的报道。

英文摘要:

The maintenance of cooperation in the presence of spatial restrictions has been studied extensively. It is well-established that the underlying graph topology can significantly influence the outcome of games on graphs. Maintenance of cooperation could be difficult, especially in the absence of spatial restrictions. The evolution of cooperation would naturally depend on payoffs. However, payoffs are generally considered to be invariant in a given game. A natural yet unexplored question is whether the topology of the underlying structures on which the games are played, possesses no role whatsoever in the determination of payoffs. Herein, we introduce the notion of cooperator graphs and defector graphs as well as a new form of game payoff, which is weakly dependent on the underlying network topology. These concepts are inspired by the well-known microbial phenomenon of quorum sensing. We demonstrate that even with such a weak dependence, the fundamental game dynamics and indeed the very nature of the game may be altered. Such changes in the nature of a game have been well-reported in theoretical and experimental studies.
