Evolving voter model

Seminar: Probability Seminar | August 29 | 3:10-4 p.m. | 332 Evans Hall

Rick Durrett, Duke University

Department of Statistics

In the evolving voter model we choose oriented edges (x,y) at random. If the two individuals have the same opinion, nothing happens. If not, x imitates y with probability 1-alpha, and otherwise severs the connection with y and picks a new neighbor at random
(i) from the graph,
or (ii) from those with the same opinion as x.
One model has a discontinuous transition, the other a continuous one.
