(a) Percolation threshold and (b) size of jump of C-NoN in correlated ER NoN with N = 10⁴, 〈k_in〉 = 2, and 〈k_out〉 = 1 for different α and β. When α ≈ −1 or α > 0.5 and β > 0, NoN becomes stable against random failure. In contrast, when −0.5 < α < 0.5 and β < 0, NoN is vulnerable to catastrophic collapse. (c) percolation threshold of M-NoN with correlated ER NoN with the same parameters as C-NoN. High α and β region is robust against random failure for M-NoN. (d) β_gen observed from realized networks at a given (α, β). The value β_gen is obtained by a linear regression.
