As one of the most widespread social dynamics, cooperative behavior is among the most
fascinating collective phenomena. Several animal species, from social insects to human …

We study how the presence of individuals with strong opinions affects a square lattice
majority-vote model with noise. In a square lattice network we perform Monte-Carlo …

We use a heterogeneous agent-based two-state sociophysics model to simulate financial
markets. Focusing on stock market trader dynamics, we propose a model with two kinds of …

In this work we study the majority-vote model with the presence of two distinct noises. The
first one is the usual noise q, that represents the probability that a given agent follows the …

In this paper, we investigate the noise benefits to maximum likelihood type estimators (M-
estimator) for the robust estimation of a location parameter. Two distinct noise benefits are …

We present a model of opinion formation where an individual's opinion is influenced by
interactions with a group of agents. The model introduces a novel bias mechanism that …

A discrete version of opinion dynamics systems, based on the Biswas–Chatterjee–Sen
(BChS) model, has been studied on Barabási–Albert networks (BANs). In this model …

In this Letter, we introduce a three-state majority vote model in which each voter adopts a
state of a majority of its active neighbors, if exist, but the voter becomes uncommitted if its …

We consider a generalized version of the majority-vote model in small-world networks. In our
model, each site of the network has noise q= 0 and q≠ 0 with probability f and 1− f …

In many real-world systems, agents' behaviors are usually coupled with environmental
changes. To model their coevolutionary process, we study a non-equilibrium model known …
