摇摆不定的选民的动态

Dynamics of Vacillating Voters

R. Lambiotte, S. Redner

摘要:

我们引入了摇摆选民模型,其中每个选民咨询两个邻居决定其状态,并改变意见,如果它不同意任何一个邻居。这种不确定性导致全局偏置朝向零磁化。在空间维度d>1时,出现反粗化,其中少数畴的线性维度L随着t^{1/(d+1)}增长。结果之一是,达成共识的时间与选民人数呈指数级关系。

英文摘要:

We introduce the vacillating voter model in which each voter consults two neighbors to decide its state, and changes opinion if it disagrees with either neighbor. This irresolution leads to a global bias toward zero magnetization. In spatial dimension d>1, anti-coarsening arises in which the linear dimension L of minority domains grows as t^{1/(d+1)}. One consequence is that the time to reach consensus scales exponentially with the number of voters.
