论文摘要
系统之间各个组件之间的资源交换对于人类的社交网络和城市和村庄网络等系统至关重要。由于各种原因，人类社会提出了金钱的概念作为资源的代理。在这里，我们扩展了我们中一个人最近提出的网络中资源依赖性模型，通过合并货币概念，以便网络的顶点可以彼此出售和购买所需的资源。我们使用配置模型将模型作为均质和异构度分布的底物并使用各种交换策略来模拟模型。我们表明，顶点的金钱中的初始异质性适中可以显着提高无标度网络的生存能力，而不是像Erdos-Renyi网络这样的同质网络的生存能力。我们的工作是了解货币存在对复杂网络中资源分配动态的影响的一步。
Exchange of resources among individual components of a system is fundamental to systems like a social network of humans and a network of cities and villages. For various reasons, the human society has come up with the notion of money as a proxy for the resources. Here we extend the model of resource dependencies in networks that was recently proposed by one of us, by incorporating the concept of money so that the vertices of a network can sell and buy required resources among themselves. We simulate the model using the configuration model as a substrate for homogeneous as well as heterogeneous degree distributions and using various exchange strategies. We show that a moderate amount of initial heterogeneity in the money on the vertices can significantly improve the survivability of Scale-free networks but not that of homogeneous networks like the Erdos-Renyi network. Our work is a step towards understanding the effect of presence of money on the resource distribution dynamics in complex networks.
