论文摘要
我们考虑了一个意见动力学模型，在随机对相互作用中，每个代理都会改变她对随机对的两种代理以及对其他某些代理的看法。此外，每个代理都属于一个组，并且该组中的意见被其平均值所吸引。在从中性意见开始的模拟中，我们观察到群体等级的出现。我们得出了一个时刻的近似，该方程提供了方程式，以统治一个群体中有关另一组代理的平均意见的演变。这个近似解释了小组层次结构的出现。
We consider an opinion dynamics model where, during random pair interactions, each agent modifies her opinions about both agents of the random pair and also about some other agents, chosen randomly. Moreover, each agent belongs to a single group and the opinions within the group are attracted to their average. In simulations starting from neutral opinions, we observe the emergence of a group hierarchy. We derive a moment approximation that provides equations ruling the evolution of the average opinion of agents in a group about the agents of another group. This approximation explains how the group hierarchy emerges.
