Simulation results for non-Markovian model D3.

(A) Proportion of six-prawn simulations () of non-Markovian model D3 with a given number of prawns moving CW over time, showing a bifurcation to either a CW or an anti-CW polarised state, with most simulations concluding with six prawns travelling in the same direction. (B) Final distribution of simulations by number of CW moving prawns for simulations with three, six and twelve prawns. Error bars represent the mean and standard deviation for each proportion as calculated from the final ten seconds of the simulations. (C) The average polarisation over time, adjusted by the expected polarisation of randomly oriented prawns, for simulations of three, six and twelve prawns.
