Figure 1

Example of the optimization process. The dependencies of the oscillation period (red triangles) and of the robustness against static noise (green crosses) on the iteration time are shown. The target period is $T_0=30$.Reuse & Permissions

Figure 2

Examples of designed networks producing oscillations with period $T=15$, optimized for robustness against (a) static random noise, (b) link deletions, and (c) node deletions. Thick red curves indicate the links and the nodes whose deletion brings a network outside of the tolerance window.Reuse & Permissions

Figure 3

Average robustness against (a) noise, (b) link deletions, and (c) removal of nodes for the ensembles of networks optimized for noise (open red circles), deletion of links (open green triangles), and deletion of nodes (open blue squares). Additionally, the respective data for the control ensembles of the networks with different periods, which have not been optimized for any kind of robustness, are displayed (upsidedown pink triangles). The maximum robustness achieved in the optimizations against each kind of noise for a given oscillation period is also shown (solid symbols). Networks are of size $N=10$ with $M=20$ links and noise level $S=0.1$. For each target period $T_0$, an ensemble of 100 designed networks is taken.Reuse & Permissions

Figure 4

Robustness against noise with different noise intensities $S$ for a designed network ensemble with $T=20$. Evolutionary optimization is done with $S=0.1$. Averages over an ensemble of 100 networks (open red circles) and maximum values (solid green circles) are shown.Reuse & Permissions
