Toward a Practical Technique to Halt Multiple Virus Outbreaks on Computer Networks
Figure 4
(a) DH network with four-colored node types, 164 enlarged hubs, and twenty seeds per type. (b) After the viruses have spread, all infected nodes are red and all susceptible isolated nodes are white. (c) Same DH network, but now with dark-pink-immunized hubs and six-colored node types. (d) Since the viruses are nearly unable to spread-there are only few red-and white-isolated nodes (other nodes not shown).
