Composition of the Influence Group in the -Voter Model and Its Impact on the Dynamics of Opinions.

Despite ample research devoted to the non-linear -voter model and its extensions, little or no attention has been paid to the relationship between the composition of the influence group and the resulting dynamics of opinions. In this paper, we investigate two variants of the -voter model with independence. Following the original -voter model, in the first one, among the members of the influence group, each given agent can be selected more than once.

Opinion Evolution in Divided Community.

Our agent-based model of opinion dynamics concerns the current vast divisions in modern societies. It examines the process of social polarization, understood here as the partition of a community into two opposing groups with contradictory opinions. Our goal is to measure how mutual animosities between parties may lead to their radicalization.
