关于平均场多数规则动力学一致时间的一个注记

A note on the consensus time of mean-field majority-rule dynamics

Damián H. Zanette

摘要:

在这项工作中,它指出,在平均场版本的多数规则观点动力学,对人口规模的共识时间的依赖性表现出两个制度。这是由群体的规模分布决定的,在每一个进化步骤中,群体聚集在一起达成协议。当群体大小分布具有有限的平均值时,先前已知的对群体大小的对数依赖性成立。另一方面,当平均群体规模发散时,共识时间和群体规模通过幂律相关。数值模拟验证了这种半定量的分析预测。

英文摘要:

In this work, it is pointed out that in the mean-field version of majority-rule opinion dynamics, the dependence of the consensus time on the population size exhibits two regimes. This is determined by the size distribution of the groups that, at each evolution step, gather to reach agreement. When the group size distribution has a finite mean value, the previously known logarithmic dependence on the population size holds. On the other hand, when the mean group size diverges, the consensus time and the population size are related through a power law. Numerical simulations validate this semi-quantitative analytical prediction.
