Figure 5.

Comparison of the optimal prevention in the 20-node model of the Seattle city, correspondent to Eq. (7) with $k=1$, computed for a particular instance of $J^{(0)}$ (leading to infection of the entire city, if not reduced) under $l_1$ (left sub-figure) and $l_2$ (right sub-figure). In each sub-graph initial instance, $J^{(0)}$, optimal correction, ${\widehat{J}}^{(\text{corr})}$, and respective optimal reduction, ${\widehat{J}}^{(\text{corr})}-J^{(0)}$, are shown at the bottom, middle and top layers respectively. Wider lines and red colors (in the red-to-dark blue color-coding) correspond to pair-wise links with higher values of J. (The Unfolding⁴² and Processing⁴³ software was used to create the figure).
