An optimal network that promotes the spread of an advantageous variant in an SIR epidemic.

Abstract excerpt

In the course of epidemics, the pathogen may mutate to acquire a higher fitness. At the same time, such a mutant is automatically in an unfavorable position because the resident virus has a head start in accessing the pool of susceptible individuals. We considered a class of tunable small-world networks, where a parameter, p (the rewiring probability), characterizes the prevalence of non-local connections, and we...
