Dynamics of bounded confidence opinion in heterogeneous social networks: concord against partial antagonism
Bounded confidence models of opinion dynamics in social networks have been actively studied in recent years, in particular, opinion formation and extremism propagation along with other aspects of social dynamics. In this work, after an analysis of limitations of the Deffuant-Weisbuch (DW) bounded confidence, relative agreement model, we propose the mixed model that takes into account two psycho...
متن کاملThe Bounded Confidence Model Of Opinion Dynamics
The bounded confidence model of opinion dynamics, introduced by Deffuant et al., is a stochastic model for the evolution of [0,1]-valued opinions within a finite group of peers. We show that as time goes to infinity, the opinions evolve into a random non-interacting set of clusters, and subsequently the opinions in each cluster converge to their barycenter; the limit empirical distribution is c...
متن کاملMulti-Level Opinion Dynamics under Bounded Confidence
Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a homogeneous confidence level. This paper proposes an extended model for a group of agents with heterogeneous confidence levels. First, a socia...
متن کاملBounded confidence and Social networks
In the so-called bounded confidence model proposed by Deffuant et al, agents can influence each other’s opinion provided that opinions are already sufficiently close enough. We here discuss the influence of possible social networks topologies on the dynamics of this model. PACS. 89.65 s 89.75 Fb
متن کاملContinuous-time Discontinuous Equations in Bounded Confidence Opinion Dynamics
This report studies a continuous-time version of the well-known Hegselmann-Krause model of opinion dynamics with bounded confidence. As the equations of this model have discontinuous right-hand side, we study their Krasovskii solutions. We present results about existence and completeness of solutions, and asymptotical convergence to equilibria featuring a “clusterization” of opinions. The robus...
