Figure 4
Typical snapshots of stationary state configuration in a square lattice.
Panels (a) and (b) are for partial- and free-subsidy policies, respectively. Other parameters: network size N = 100 × 100, c = 0.5, β = 1.0 and δ = 0.4. Blue, green, yellow and red points represent free-riders (not vaccinated and healthy), imitated vaccinators, infected individuals and freely vaccinated donees, respectively.
