Video S2 Another SIR epidemic on the artificial social network. In this video, another SIR epidemic starts from a different seed on the artificial Jin-Girvan-Newman social network with N = 1,000 nodes, 1,584 links, average degree ,k. = 3.168 and clustering coefficient C = 0.3928. The transmission probability for this SIR epidemic remains at p = 0.80, and infected nodes again recover after t R = 1 time step. (WMV)
