Initialization of individual velocity. Assuming the individual position is as shown in (b), according to the position, the edges (a1, a3) and (a2, a3) are conserved; the nodes a1, a2, and a3 are conserved; thus, the velocity of these nodes is 0. Therefore, the individual velocity can be obtained as shown in (c).
