Emergence of Simple Characteristics for Heterogeneous Complex Social Agents

Eric Bertin

Models of interacting social agents often represent agents as very simple entities with a small number of degrees of freedom, as exemplified by binary opinion models for instance. Understanding how such simple individual characteristics may emerge from potentially much more complex agents is thus a natural question. It has been proposed recently in [E. Bertin, P. Jensen, C. R. Phys. 20, 329 (2019)] that some types of interactions among agents with many internal degrees of freedom may lead to a ‘simplification’ of agents, which are then effectively described by a small number of internal degrees of freedom. Here, we generalize the model to account for agent intrinsic heterogeneity. We find two different simplification regimes, one dominated by interactions, where agents become simple and identical as in the homogeneous model, and one where agents remain strongly heterogeneous although effectively with simple characteristics.

异构复杂社会代理的简单特征的出现

交互社会代理的模型通常将代理表示为具有少量自由度的非常简单的实体,例如二元意见模型。因此,了解这些简单的个体特征如何从可能更复杂的代理中出现是一个自然的问题。最近在 [E. Bertin, P. Jensen, CR Phys. 20, 329 (2019)] 指出,具有许多内部自由度的代理之间的某些类型的交互可能会导致代理的“简化”,然后通过少量内部自由度有效地描述代理。在这里,我们概括了模型以解释代理的内在异质性。我们发现了两种不同的简化机制,一种由交互主导,其中代理变得简单且与同构模型中的相同,
