4.7 Flocking

A flocking model loosely based on ideas in

Czirók A and Vicsek T 2000 Collective behavior of interacting self-propelled particles. Physica A: Statistical Mechanics and its Applications 281 17–29.

Grégoire G, Chaté H and Tu Y 2003 Moving and staying together without a leader. Physica D: Nonlinear Phenomena 181 157–70.

Vicsek T, Czirók, A. A, Ben-Jacob E, Cohen I and Sochet O 1995 Novel type of phase transition in a system of self-driven particles. Physical Review Letters 75 1226–29.

This model also includes various different implementations of the idea of ‘flock-mates’ which demonstrate the importance of basic spatial properties (in this case proximity or ‘neighbourhood’) in many spatial models.
