Let s have a party — •Marian Brandau and Steffen Trimper — Fachbereich Physik, Martin-Luther-Universität, Friedemann-Bach-Platz, 06108 Halle

We consider a homogeneous population of N agents which are interested in a party. Based on a simple model we analyse the behaviour of such a meeting particularly with regard to the appearance of a depletion effect. The agents evaluate their party by the comparison of their party with any other party. We take as criterion the number of friends at the several parties. The friends of each agent are exponentially distributed. After this proceeding they take the decision, either they stay on the party or they leave it and go to another one. Due to this interaction effects a collective movement will lead to enrich or become extinct of some parties. The simulations on a network show such an effect depending on the initial condition and the distribution of friends. In some cases all agents accumulate at one party at the end of the simulation. The simulations are confronted with an analytical approach based on an evolution model.
