Figure 4.

Dependence of the observed cases on the fraction of active inputs $I$. For the upper figure, the clustering parameter was set to $d=1$ which means that all defective nodes form one cluster. Contrarily, in the lower figure, the parameter was set to $d=0$, leading to a broad distribution of the defective nodes. For each parameter combination, the system was simulated 100 times for 1000 time steps. The colour code (as defined in Fig. 1a) indicates, which cases occurred in the time line. Here, Cx and Dx denote that the time line also contained the cases (A, B) or (A, B, C), respectively. Curves for other sets of parameters are provided in the supplement.
