Figure 4
Entropy rate h as a function of α for six real networks with the well defined fractal dimension.
The maximum of entropy rate occurs at position of αopt = 3.9 (Dolphin), 5.7 (C. elegans), 5.5 (E. coli), 5.6 (E-mail), 4.5 (Power grid) and 5 (North America), respectively, marked by the solid lines. Their fractal dimensions are df = 1.88 (Dolphin), 3.7 (C. elegans), 3.45 (E. coli), 3.69 (E-mail), 2.42 (Power grid) and 3 (North America), with reference to20,28,29,30,35.
