Social evolution—Contour plots of R based on the level of manual tracing overlap Γ and digital tracing uptake r , for different p a values.

The results here correspond to the data-driven Social Evolution network when η = .001, with each pair of charts describing p a = 0.2 on the left and p a = 0.5 on the right. Each line represents a different testing level τ r , while the columns showcase combinations of one p a value together with a level of tracing effort given by τ t .
