Phase coexistence in the fully heterogeneous Hegselmann–Krause opinion dynamics model

We have performed extensive simulations of the heterogeneous HK model where the connections among the agents are constrained by different types of networks.

Each society is characterized by a set of variables representing the confidence of each agent i, \(\varepsilon _i\), uniformly distributed in the interval \([\varepsilon _l,\varepsilon _u]\), representing the range of open-mindedness of the society. The confidences are fixed in time as they represent an idiosyncratic property of the agents. This is the equivalent of a quenched disorder in physical systems. Moreover, social ties are…
