Abstract
In the compromise model of Deffuant et al., opinions are real numbers between 0 and 1, and two agents are compatible if the difference of their opinions is smaller than the confidence bound parameter ∊. The opinions of a randomly chosen pair of compatible agents get closer to each other. We provide strong numerical evidence that the threshold value of ∊ above which all agents share the same opinion in the final configuration is 1/2, independently of the underlying social topology.

A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.

An opinion dynamics model in which agents reach compromise via pairwise interactions is studied, in which major and minor parties emerge, and these are organized in alternating pattern.
