Data collapse plot of (a) the average occupation number m_k versus kρ^δ_c at the transient time t = 2¹⁰, (b) the evolution of ratio of IPR to its steady state limit, I_t/I_∞, versus t/ρ^ν, with ν = 1 – δ being the dynamic exponent in the relaxation dynamics, at δ = 0.2 for network size L = 4000, and various densities ρ = 0.5 (purple open diamonds), ρ = 2 (blue open triangles), ρ = 10 (red open squares), and ρ = 50 (green open circles), respectively.
