Collective Behaviour

Collective behavior is often the result of self organzation, as can be illustrated in terms of simple models of flocking of "boids", of hiererchy development in social networks or of development of fashions in society. Often positive feedback are involved, and playing simple games with mechanism of positive feedbacks can give new insight.
