We propose a modification in the Sznajd sociophysics model defined on the square lattice.
For this purpose, we consider reputation—a mechanism limiting the agents' persuasive …

We analyze the critical behavior of a class of discrete opinion models in the presence of
disorder. Within this class, each agent opinion takes a discrete value (±1 or 0) and its time …

We propose a model of opinion dynamics which describes two major types of social
influence—conformity and independence. Conformity in our model is described by the so …

A recently proposed model of social interaction in voting is investigated by simplifying it
down into a version that is more analytically tractable and which allows a mathematical …

The Sznajd model, where two people having the same opinion can convince their neighbors
on the square lattice, is modified in the sense of Deffuant et al. and Hegselmann, that only …

We propose a model to simulate the process of opinion formation in a society where the
traditional division into leftists and rightists is not enough any longer. The model is based on …

We propose a variant of the voter model by introducing the social diversity in the evolution
process. Each individual is assigned a weight that is proportional to the power of its degree …

In less than a year, the Sznajd model has found several applications. In this model, an
isolated person does not convince others; a group of people sharing the same opinions …

We propose a collective opinion formation model with a so-called confirmation bias. The
confirmation bias is a psychological effect with which, in the context of opinion formation, an …

The opinion dynamics studies how a final consensus emerges from a diversified initial
configuration. The final result can be an artifact arising in the voting processes and overlook …
