ONGOING PROJECTSSelf-organization of Coevolutionary Networks
Daichi Kimura and Yoshinori Hayakawa, June 2008
|We have investigated a simple coevolutionary network model incorporating
three processes - changes of opinions, homophily and heterophily. In this
model, each node holds one of G opinions and changes its opinion like the
voter model. Homophily is a tendency that connections form between individuals
of same opinions and heterophily is an opposite effect. If there is no
heterophily, this model corresponds to the Holme and Newman's model (Phys.
Rev. E 74, 056108). We show that the behavior of this model without heterophily
can be understood in terms of a mean field approximation. We also find
that this model with heterophily exhibits topologically complicated behaviors
such as small-world property.
