Dependence of σ on D for different average degrees 〈 k 〉 at ɛ = 0.1 and τ = 24. As 〈 k 〉 increases, the σ peaks grow and become highest at around 〈 k 〉 = 8, and then become low again. This indicates that there is an optimal average degree with which the synchronization transitions by channel noise become strongest.
