Spontaneous group formation in the seceder model

The seceder model shows how the local tendency to be different gives rise t o the formation of groups. The model consists of a population of simple ent ities which reproduce and die. In a single reproduction event three individ uals are chosen randomly and the individual which possesses the largest dis tance to their center is reproduced by creating a mutated offspring. The of fspring replaces a randomly chosen individual of the population. The paper demonstrates the complex group formation behavior and its dependency on the population size.
