基于中心性网络的博弈论构造

Game Theoretic Formation of a Centrality Based Network

Ryan Tatko, Christopher Griffin

摘要:

我们将网络的形成建模为一个游戏,在这个游戏中,玩家渴望通过增加与他们路径相连的其他玩家的数量来最大化自己的中心性,同时为每个增加的相邻边缘带来成本。我们模拟玩家之间的互动使用的算法,在理性的战略行为的基础上,一个共同的目标函数的因素。由此产生的网络表现出成对的稳定性,从中我们得到必要的稳定条件,为特定的图形拓扑结构。然后,我们扩展模型来模拟大量玩家的非平凡游戏。我们表明,使用必要的条件,为稳定的星形拓扑结构,我们可以诱导形成枢纽球员,积极影响网络的总福利。

英文摘要:

We model the formation of networks as a game where players aspire to maximize their own centrality by increasing the number of other players to which they are path-wise connected, while simultaneously incurring a cost for each added adjacent edge. We simulate the interactions between players using an algorithm that factors in rational strategic behavior based on a common objective function. The resulting networks exhibit pairwise stability, from which we derive necessary stable conditions for specific graph topologies. We then expand the model to simulate non-trivial games with large numbers of players. We show that using conditions necessary for the stability of star topologies we can induce the formation of hub players that positively impact the total welfare of the network.
