The connected component size distributions observed in pooled (see “Methods” section) simulations of network growth based on UCM and PCM growth models. In all cases we used the parameter f=0.5 and δ values listed in the legend. An orange guide to the eye line is added to illustrate the slope observed in the connected component size distribution of the SD network (p(N)∝N^−2.7). a. The component size distributions observed in the UCM simulations differ from the one observed in the SD network. Both slopes are different and no peaks that correspond to giant components are observed in the UCM simulated networks. b. The component size distributions observed in the PCM simulated networks are similar to the one of the SD network. All distributions independently of δ value follow a similar slope on a log-log scale to the one of the SD network for component sizes observed in the SD network. Moreover, both the PCM synthetic networks and the SD network include giant components. It can be seen as a peak at the right side of the component size distributions of the PCM simulated networks
