FIG. 2.

The order parameter $r$, as a function of $T$, for (a) the RGs and (b) the SFNs. Here $f$ is set to $f=0.01$ (open symbols) and 0.2 (solid symbols). The red circles, green triangles, and blue squares represent the results for the quarantine measure, the random vaccination, and the acquaintance vaccination, respectively. The black line represents the result of the original SIR model. In (a), the open green triangles (random vaccination with $f=0.01$) fall behind the open blue squares (acquaintance vaccination with $f=0.01$).
