Order-disorder transition for the Vicsek model at different $v$ values (solid lines) and the network of fixed vectors of 1 (dashed line), both with angular noise. (a) Time-averaged order parameter $⟨\psi ⟩$ vs noise strength $\eta$. (b) Same as (a) for the Binder cumulant $G=1-⟨{\psi }^2{⟩}^2/⟨{\psi }^4⟩$. For the VM, $\rho =2$, and $v=5$ (○), $v=10$ (□), $v=20$ (▵) with $L=200$, 250, and 300, respectively. For the network, the number of nodes is $N=4\times {10}^5$ and the average connectivity is set to $K=2\pi$ (i.e., each node interacts with 6 or 7 neighbors, with suitable probabilities), which corresponds to $\rho =2$ in the VM.Reuse & Permissions
