The influence of different updating methods on the dynamics of Kauffman networks — •Florian Greil and Barbara Drossel — Institut für Festkörperphysik, Technische Universität Darmstadt

We consider the influence of different updating schemes on the dynamics of random Boolean networks. The standard synchronous updating rule, which is usually chosen, is compared with stochastic and deterministic asynchronous rules. For the asynchronous stochastic update and certain types of asynchronous deterministic update, the number of attractors in a critical Boolean network grows like a power law with the system size. The mean size of the attractors increases as a stretched exponential. This is in strong contrast to the synchronous case.
