论文摘要
最近，已经提出了一个基于同质的评估动力与基于影响力的意见动力学之间相互作用的模型。该模型首次探讨了一组代理商对一定数量的问题/主题的看法如何受代理商的相互评估的影响，相反，根据代理商对各种问题的看法，对代理商的相互评估进行了更新。在本文中，我们表明，模型的简化（并且在某些情况下更可行）版本仅解释了代理人评估的迹象，而不是其数值值，它提供了小型网络中意见动态的同样准确有效的模型。该模型达到的平衡几乎可以肯定地与代理网络完整且结构平衡的情况相对应。另一方面，我们确保可以按照有限的步骤来达到这种e骨，并且与原始模型不同，我们排除了与断开的社交网络相对应的其他类型的平衡。
Recently a model for the interplay between homophily-based appraisal dynamics and influence-based opinion dynamics has been proposed. The model explores for the first time how the opinions of a group of agents on a certain number of issues/topics is influenced by the agents' mutual appraisal and, conversely, the agents' mutual appraisal is updated based on the agents' opinions on the various issues, according to a homophily model. In this paper we show that a simplified (and, in some situations, more feasible) version of the model, that accounts only for the signs of the agents' appraisals rather than for their numerical values, provides an equally accurate and effective model of the opinion dynamics in small networks. The equilibria reached by this model correspond, almost surely, to situations in which the agents' network is complete and structurally balanced. On the other hand, we ensure that such equlibria can always be reached in a finite number of steps, and, differently from the original model, we rule out other types of equilibria that correspond to disconnected social networks.
