    <p>Fitness and penalty curves as a function of iterating generation for (a) ER with ⟨k⟩ = 4.0, (b) SF with ⟨k⟩ = 4.0 and γ = 2.1, and (c) SW with ⟨k⟩ = 4.0. The red dotted line with a square is the best fitness corresponding to D<sub>best</sub> at the current generation, the blue dashed line with a circle is the mean fitness of all control schemes at each generation, and the black line with a triangle is the penalty term corresponding to D<sub>best</sub> at each generation.</p

    <p>Red stars represent the node in-degree denoted by ⟨k<sub>in</sub>⟩ and the green diamonds represent the node out-degree denoted by ⟨k<sub>out</sub>⟩. (a) Random regular networks with homogeneous degree distribution of ⟨k<sub>in</sub>⟩ = ⟨k<sub>out</sub>⟩ = 4. (b) ER random networks with Poisson degree distribution; the degree heterogeneities rely on the average degree denoted by ⟨k⟩. (c) SF networks with power-law degree distribution, which results in large degree heterogeneities. (d) SW networks with long-tail degree distribution, which decreases much slower than the SF distribution.</p
