Pseudocode and graphical explanation for the LS algorithm. We use the same coloring as in Fig. 2a. Black edges show the queried edges, a node with black cross (X) marks a negative test result, and red stroked node marks the node currently maintained as source candidate by the LS algorithm. We denote by \(t_v\) the symptom onset time of symptomatic node v and by H(v) the household of a node v similarly to the main text
