How to convince others ? Monte Carlo simulations of the Sznajd model

摘要

In the Sznajd model of 2000, a pair of neighbouring agents on a squarelattice convinces its six neighbours of the pair opinion if and only if the twoagents of the pair share the same opinion. It differs from other consensusmodels of sociophysics (Deffuant et al., Hegselmann and Krause) by havinginteger opinions like $\pm 1$ instead of continuous opinions. The basic resultsand the progress since the last review are summarized here.
