Vicsek model

Behaviour of Vicsek model as a function of alignment noise.
In the Vicsek model of collective behaviour, each "bird" tries to align its direction without other birds within a given radius. To model imperfections in perception, perfect alignment is offset with added noise. The strength of the noise determines how well each bird is able to align itself with its neighbourhood. Zero noise corresponds to perfect instantaneous alignment. For maximum noise, the direction of the birds at each time step changes in a uniformly random way, preventing any sort of alignment.
