梯形图上某些二选多人博弈的纳什均衡

Nash Equilibria in certain two-choice multi-player games played on the ladder graph

Victoria Sánchez Muñoz, Michael Mc Gettrick

摘要:

在这篇文章中,我们分析计算纳什均衡(NE)的两个选择游戏(圆形)梯形图上的$2n$的球员。我们考虑了一组具有通用支付参数的游戏,唯一的要求是,如果玩家选择相反的策略(反协调游戏),就会发生NE。结果表明,无论是阶梯还是圆形阶梯,NE的数量都随着$n$的数量(一半)呈指数增长,即$N_{NE}(2n)\sim C(φ)^n$,其中$φ=1.618..$是黄金分割比,$C_{circ}>C_{ladder}$是最大值。此外,比例因子$C_{ladder}$的值取决于支付参数的值。然而,对于循环梯形图(3度图),这不再是真的,即$C_{circ}$是常数,这可能表明图的拓扑结构对于设置NE的数量确实起着重要的作用。

英文摘要:

In this article we compute analytically the number of Nash Equilibria (NE) for a two-choice game played on a (circular) ladder graph with $2n$ players. We consider a set of games with generic payoff parameters, with the only requirement that a NE occurs if the players choose opposite strategies (anti-coordination game). The results show that for both, the ladder and circular ladder, the number of NE grows exponentially with (half) the number of players $n$, as $N_{NE}(2n)\sim C(φ)^n$, where $φ=1.618..$ is the golden ratio and $C_{circ}>C_{ladder}$. In addition, the value of the scaling factor $C_{ladder}$ depends on the value of the payoff parameters. However, that is no longer true for the circular ladder (3-degree graph), that is $C_{circ}$ is constant, which might suggest that the topology of the graph indeed plays an important role for setting the number of NE.
