We examine an opinion formation model, which is a mixture of Voter and Ising agents. Numerical simulations show that even a very small fraction (∼1%) of the Ising agents drastically changes the behavior of the Voter model. The Voter agents act as a medium, which correlates sparsely dispersed Ising agents, and the resulting ferromagnetic ordering persists up to a certain temperature. Upon addition of the Ising agents, a logarithmically slow coarsening of the Voter model (d=2), or its active steady state (d=3), change into an Ising-type power-law coarsening.
我们研究了一种观点形成模型，它是投票者和伊辛模型的混合体。数值模拟表明，即使是很小一部分（约 1%）的伊辛模型也会极大地改变投票者模型的行为。投票者模型充当一种介质，它使稀疏分布的伊辛模型相关联，并且由此产生的铁磁有序状态一直持续到一定温度。加入伊辛模型后，投票者模型的对数缓慢粗化（d=2），或其活跃的稳态（d=3），会转变为伊辛型幂律粗化。
