Configuration-field approximation, with the vector fields of the dynamics of the three feasible strategies (Lazy, trusty, Smart) in four different cases. A Lazy is the only fixed point of the dynamics; parameters are \(b=0.3, r=0.01\). B The monomorphic Lazy and the polymorphic Smart/Lazy states are the stable fixed points of the dynamics; \(b=0.5, r=0.01\). C The monomorphic Lazy and the polymorphic Trusty/Lazy states are the stable fixed points of the dynamics; \(b=0.65, r=0.2\). D The monomorphic Lazy and the polymorphic Smart/Lazy states are the stable fixed points of the dynamics; \(b=0.6, r=0.01\). All CF systems admit multiple unstable fixed points as well, including the Smart and the Trusty corners of the state space. In all cases, the rest of the parameters are \(N=9, \kappa =3, {c}_{0}=1,c=0.3\)
