空间公共物品博弈中噪声对合作的拓扑无关影响

Topology independent impact of noise on cooperation in spatial public goods games

摘要:

我们研究了在不同的规则图上的公共产品博弈中合作的演化,作为噪声水平的函数,潜在的策略采用。我们专注于不同群体规模的公共产品游戏中,个人参与所带来的影响,揭示了更大的群体的球员可能会导致定性不同的行为时,接近确定性的限制策略采用。虽然通过成对的相互作用的中间不确定性的策略采用可能会确保最佳条件的生存合作者在一个特定的图形拓扑结构,更大的群体保证这只在附近的确定性限制独立于底层图形。造成这些差异的原因是,在较大的集团内共同加入,使原本没有直接联系的行为者之间存在间接联系。因此,我们表明,增加组的大小可能会引入一个有效的过渡的相互作用拓扑结构,后者的形状的噪声依赖的情况下,成对的相互作用的合作的演变。

英文摘要:

We study the evolution of cooperation in public goods games on different regular graphs as a function of the noise level underlying strategy adoptions. We focus on the effects that are brought about by different group sizes of public goods games in which individuals participate, revealing that larger groups of players may induce qualitatively different behavior when approaching the deterministic limit of strategy adoption. While by pairwise interactions an intermediate uncertainty by strategy adoptions may ensure optimal conditions for the survival of cooperators at a specific graph topology, larger groups warrant this only in the vicinity of the deterministic limit independently from the underlying graph. These discrepancies are attributed to the indirect linkage of otherwise not directly connected players, which is brought about by joint memberships within the larger groups. Thus, we show that increasing the group size may introduce an effective transition of the interaction topology, and that the latter shapes the noise dependence of the evolution of cooperation in case of pairwise interactions only.
