Figure 5  Simulation results for government’s trade-off in blocking. (a) conveys the distributions of optimal blocking threshold under 484 different external scenarios (4 pieces of initial information, 11 individual thresholds, and 11 disclosing thresholds). We show how the figure works by taking the first column as an example: there are 98 conditions in which 0 is the lowest infection rate; (b) conveys the relationship between initial information and blocking threshold; and (c) conveys the relationship between individual threshold and blocking threshold.
