The Sznajd model of consensus building with limited persuasion

摘要

The Sznajd model, where two people having the same opinion can convince their neighbors on the square lattice, is modified in the sense of Deffuant et al. and Hegselmann, that only neighbors of similar opinions can be convinced. Then consensus is easy for the competition of up to three opinions but difficult for four and more opinions. [References: 18]
