Fig 8. Cores of the 8 principal clusters, on a SL attractor set.

The initial attractors set contains 28,849 attractors, with P = 1 and G = 900. The clusters are obtained by a double-pass clustering, with inclusion match similarity (k = 0.8). The cores are defined as the 10% most active nodes in a cluster. a: core of cluster 1 (4,089 attractors); b: core of cluster 2 (3,048 attractors); c: core of cluster 3 (2,045 attractors); d: core of cluster 4 (1,573 attractors); e: core of cluster 5 (907 attractors); f: core of cluster 6 (892 attractors); g: core of cluster 7 (881 attractors); h: core of cluster 8 (844 attractors).
