A simple Ising spin model which can describe a mechanism of making a decision in a closed community is proposed. It is shown via standard Monte Carlo simulations that very simple rules lead to rather complicated dynamics and to a power law in the decision time distribution. It is found that a closed community has to evolve either to a dictatorship or a stalemate state (inability to take any common decision). A common decision can be taken in a "democratic way" only by an open community.

Opinion evolution in open community
A dynamic group composed with a constant number of people and the people will change periodically, the open system can reach a democracy-like steady state as long as the updating frequency and updating proportion are appropriate.
A simple Ising spin model, which can describe the mechanism of price formation in financial markets is proposed. In contrast to other agent-based models, the influence does not flow inward from the
Opinion dynamics in a three-choice system
Abstract.We generalize Galam’s model of opinion spreading by introducing three competing choices. At each update, the population is randomly divided in groups of three agents, whose members adopt the
Kinetic model for multidimensional opinion formation.
A kinetic model to describe the evolution of the opinion in a closed group with respect to a choice between multiple options, which takes into account two main mechanisms of opinion formation, namely, the interaction between individuals and the effect of the mass media.
Compromise and synchronization in opinion dynamics
The Opinion Changing Rate (OCR) model, which allows to study under which conditions a group of agents with a different natural tendency to change opinion can find the agreement, is discussed.
Spontaneous Reorientations In A Model Of Opinion Dynamics With Anticonformists
A model, based on the idea of the outflow dynamics, is investigated, in which only conformity and anticonformity can lead to the opinion change, and it is shown that for low level of anticonforming the consensus is still reachable but spontaneous reorientations appear.
Dynamic scaling regimes of collective decision making
A social system of agents faced with a binary choice, of nonequilibrium type, converging to a final decision is investigated, which finds two distinct regions in terms of the finalizing time, on random graphs and scale-free networks.
Opinion Formation in the Kinetic Exchange Models
We review the minimal multi-agent model (LCCC) for the collective dynamics of opinion formation in the society, which was based on the kinetic exchange dynamics studied in the context of income,

This paper studies the several models of opinion dynamics aiming to offer referential information for the evolution of opinion and represents that social networks have necessary stability.
Opinion dynamics on an adaptive random network.
The classical model for voter dynamics in a two-party system with two basic modifications is revisited and criteria to determine whether consensus or polarization will be the outcome of the dynamics and on what time scales these states will be reached are established.

A simple and robust model of biological evolution of an ecology of interacting species that self-organizes into a critical steady state with intermittent coevolutionary avalanches of all sizes and exhibits ``punctuated equilibrium'' behavior.
Modelling collective opinion formation by means of active Brownian particles
Abstract:The concept of active Brownian particles is used to model a collective opinion formation process. It is assumed that individuals in community create a two-component communication field that
Optimizing conflicts in the formation of strategic alliances
Abstract:Coalition setting among a set of actors (countries, firms, individuals) is studied using concepts from the theory of spin glasses. Given the distribution of respective bilateral propensities
Self-organized criticality: An explanation of the 1/f noise.
We show that dynamical systems with spatial degrees of freedom naturally evolve into a self-organized critical point. Flicker noise, or 1/f noise, can be identified with the dynamics of the critical
Dynamical structure factor for multiple-well configurations
Some general characteristics of the classical dynamic structure factor S(k, omega ) corresponding to a one-dimensional multiple-well potential are analysed. A rich peak structure is shown to emerge
The psychology of social impact.
The author proposes a theory of social im- pact specifying the effect of other persons on an in- dividual. According to the theory, when other people are the source of impact and the individual is
