Generic Absorbing Transition in Coevolution Dynamics [PDF]
Physical Review Letters, 2008 We study a coevolution voter model on a network that evolves according to the state of the nodes. In a single update, a link between opposite-state nodes is rewired with probability $p$, while with probability $1-p$ one of the nodes takes its neighbor's state.
