The sum of positive LEs with respect to the number of nodes for networks with star topology that do not satisfy cases 1 and 2, respectively. For each network we considered the building block with N0=5 and ε=2·10−4. In (a) the inter-coupling of the network Ω(1) is γ(1)=0.05 and in (b) γ(1)=0.5045 and k=[1,2,…,6]. In both graphs, during the evolutionary process the inter-coupling strength was kept constant. The fitting in the orange line in (a) produces p1=0.5223 and p2=3.3490, where p1 is the slope and p2 is the constant coefficient of the fitting
