A model for repelling/anti-aligning self propelled particles.
- The orientation update rule is asynchronous as opposed to the synchronous update rule implemented in traditional Vicsek model.
- The particle orientation are sequentially updated in the first step in a random order. The average orientation of a particle's neighbourhood - defined as a circle of radius R centered around the particle - is evaluated and the said particle assumes an orientation = (average + pi). The pi terms effectuates a repulsive inter-particle interaction.
- In the second step, all particles move simultaneously.
- Third step, the particle order is shuffled randomly
The steady state picture: Two alternating lanes consisting of particle clusters, moving in opposite directions respectively.
