Infected agents ($I$) and defectors strategy fraction ($D$) time evolution. The horizontal line represents the value $I^{\prime }=\Omega /\delta {\beta }_N$. The vertical dashed lines indicate when $I\left(t\right)=I^{\prime }$. As expected, these are the strategy maximum and minimum values. Here $\delta =10,{\beta }_N=5$.
