Abstract

In this paper, we study the opinion dynamics of Improved Deffuant model (IDM), where the convergence parameter is a function of the opposite’s degree according to the celebrity effect, in small-world network (SWN) and scale-free network (SFN). Generically, the system undergoes a phase transition from the plurality state to the polarization state and to the consensus state as the confidence parameter increasing. Furthermore, the evolution of the steady opinion as a function of , and the relation between the minority steady opinion and the individual connectivity also have been analyzed. Our present work shows the crucial role of the confidence parameter and the complex system topology in the opinion dynamics of IDM.
