Figure 3. Stability of groups and effect of initial conditions.

(A) Number of stable groups 〈N_sg〉, calculated in a time window of length τ = 50, as a function of the collision rate p_c, for different values of K and R. (B) Average groups size 〈S(t)〉 (main) and average number of moving individuals 〈N_m(t)〉 (inset) as a a function of time t, for different initial conditions: random values of position and status, same position and random status, same position and status.
