Before revision:  Successful convergence of this process depends crucially on network topology and is most efficient for scale-free connectivity , typical of gene regulatory networks. For such networks, convergence to an adapted phenotype can be achieved without fine tuning of initial conditions or other model parameters, thus making it plausible for biological implementation  .
