Behaviour of the approximative search of Algorithm 1 for $N=\{14,20,26\}$ and $k=\{11,17,23\}$. The spectral density ${\varphi }_{{\mathcal{G}}^{\prime }}$ describing graph evolutions not leading to transient amplifiers and the quantity $|{\varphi }_{\mathcal{G}}-{\varphi }_{{\mathcal{G}}^{\prime }}|$ describing the difference between ${\varphi }_{\mathcal{G}}$ and ${\varphi }_{{\mathcal{G}}^{\prime }}$.
