doc=Another increase in <math>r</math> turns the interior fixed point <math>Q</math> into a stable node. As before, cooperators and defectors co-exist at some fixed densities only, they no longer approach the equilibrium in an oscillatory manner. Severe exploitation and low population densities again result in extinction.

The parameters are <math>r = 5</math>, <math>N = 8</math>, <math>c = 1</math>, <math>b = 0</math>, <math>d = 0.5</math> using numerical integration of the replicator equation.}}
