Figure 3From: Beyond just “flattening the curve”: Optimal control of epidemics with purely non-pharmaceutical interventionsPlot of the cost functions for (a) minimal intermediate costs and (b) the enforcement of herd immunity at the end of the intervention for different values of ε. We use the short notation \(X=\mathcal{R}_{0}S (T )/N (T )\). The shaded region corresponds to unstable terminal statesBack to article page
