Binary and multivariate stochastic models of consensus formation are discussed. The voter model, which is the simplest model of collective behavior, is defined by a set of voters who have two opinions or spins at a network's nodes. The elementary dynamical step consists of randomly choosing a node and assigning it the opinion or spin value of one of its nearest neighbors, also chosen at random. This opinion-formation mechanism reflects the agents' complete lack of self-confidence and could be appropriate for describing processes of opinion formation in certain groups in which imitation is prevalent. Axelrod Model, in which order-disorder transition becomes system-size dependent, is also discussed.
