Fig 9. Cores of the 8 principal clusters, on a DG attractor set.

The initial attractors set contains 36,459 attractors, with P ∈ [0.5;7] 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 (11,141 attractors); b: core of cluster 2 (6,376 attractors); c: core of cluster 3 (5,494 attractors); d: core of cluster 4 (2,833 attractors); e: core of cluster 5 (2,832 attractors); f: core of cluster 6 (1,347 attractors); g: core of cluster 7 (1,275 attractors); h: core of cluster 8 (1,236 attractors).
