A modified one-dimensional Sznajd model

Abstract

The Sznajd model is an Ising spin model representing a simple mechanism of making up decisions in a closed community. In the model each member of the community can take two attitudes A or B represented by a spin up or spin down state respectively. It has been shown that, in one-dimension starting from a totally random initial state, three final fixed points can be obtained; all spins up, all spins down or an antiferromagnetic state in which each site take a state which is opposite from its two nearest neighbors. Here, a modification of the updating rule of the Sznajd model is proposed in order to avoid such antiferromagnetic state since it is considered to be an unrealistic state in a real community.
