Stochastic cycle selection in an asymmetric bridgeless cubic graph on 21 edges. The graph shows an integration of the active network model on the graph shown in Fig. 3B (graph 19 of Fig. S4) up to t=1.6×106, played back such that 1 s is Δt=72,000. Flowing edges above |ϕe|>1/2 are cyan, nonflowing edges fluctuate from white at |ϕe|=0 to gray at |ϕe|=1/2. Parameters are λ=2.5, μ=25, and β−1=0.05.
