We investigate the dependence of steady-state properties of Schelling’s segregation model on the agents’ activation order. Our basic formalism is the Pollicott-Weiss version of Schelling’s segregation model. Our main result modifies this baseline scenario by

1. employing a log-linear response rule, similar to the setup in Zhang (Journal Ec. Behavior and Organization 2004)

2. incorporating „contagion” in the decision to move: agents are connected by a second, „word-of-mouth”, network. Agents’ activation is specified
by a random walk on this network.

Our results are an example of the adversarial scheduling approach to social simulations.
