狂热者在自适应选民模型中的作用

Role of Zealots on the Adaptive Voter Model

Ka Wai Cheung, Chung Him Liu, Kwok Yip Szeto

摘要:

选民模型作为一种意见动态模型已经被广泛研究,而狂热者的作用只是最近才被讨论。我们介绍了自适应选民模型与狂热者,并表明,最终的磁性分布可以分为两个区域,这取决于狂热者的数量以及形成链接的概率。当狂热者的分数占主导地位的人口,磁的概率分布遵循高斯分布和弛豫时间是人口规模无关。当种群由敏感因子控制时,弛豫时间与种群大小的指数成正比。我们在极限情况下得到了弛豫时间的解析解,并利用近似方法解释了这两个区域弛豫时间的差异。

英文摘要:

The voter model has been extensive studied as an opinion dynamic model, and the role of the zealots has only been discussed recently. We introduce the adaptive voter model with zealots and show that the final distribution of the magnetism can be separated into two regions depending on the number of zealots as well as the probability of forming link. When the fraction of zealots is dominated in the population, the probability distribution of magnetism follows a Gaussian-like distribution and the relaxation time is population-size independent. When the population is dominated by the susceptible agents, the relaxation time is proportional to the exponential of the population size. We have found the analytical solution of the relaxation time in the limiting cases and explained the difference of the relaxation time in these two regions based on the approximation method.
