First, communication regimes are introduced as an elementary concept of opinion dynamic models. Second, we develop a model that covers two major models of continuous opinion dynamics, i.e. the basic model of Deffuant and Weisbuch as well as the model of Krause and Hegselmann. To combine these models, which handle different numbers of communicating agents, we convert the convergence parameter of Deffuant and Weisbuch into a parameter called self-support. Third, we present simulation results that shed light on how the number of communicating agents but also how the self-support affect opinion dynamics. The fourth contribution is a theoretically driven criterion when to stop a simulation and how to extrapolate to infinite many steps.15 pages, 6 figures, In: Proceedings of the Second Conference of the European Social Simulation Association (ESSA), September 16-19, Valladolid, Spain, 2004 (ISBN 84-688-7964-9)Physics and SocietyCommunication regimes in opinion dynamics: Changing the number of communicating agentstext
