Fig. 8
The subplot (a) shows an instant distribution of the automata, their velocities and comet tails trajectories found at time moment \(t_{1} > \tau\) starting from a common center with random (uniform in average) distribution of the initial body orientations. The subplots (b), (c) and (d) show the positions of the heads and the trajectories, obtained at relatively late time moment \(t_{2} > > t_{1}\) for the weak, intermediate and strong potentials, respectively. The trajectories in these subplots are colorized by the time elapsed from the beginning of motion (later time moments correspond to the red colour and earlier to the blue one, respectively). Red fragments of the trajectories, which cover the blue ones in the central part of the subplot (c), correspond to the returns of the automata into the area of their origination, which happened at late stages of the motion (see also Supplementary Movie 3).
