FIG. 6. Top: Parameter regions for the model considered in the main text, with N ¼ 10 3 and h k i ¼ 2 E=N ¼ 20 . Each curve corresponds to one value of B and separates a region above where the nonoverlapping model is preferred from a region below where the overlapping model is chosen. Bottom: Networks and their preferred partitions, corresponding to parameter values indicated in the top
