Video S4 SIR epidemic on the EGP-immunized artificial social network. II. In this video, we start an SIR epidemic from a second seed on the EGP-immunized artificial Jin-Girvan-Newman social network. The original network consists of 1,000 nodes and 1,584 links, whereas the estimated network EGP is based on consists of 475 nodes and 934 links. 67 separator nodes identified by the EGP procedure are removed from the original network, giving an immunized network with 1,359 links.
