a There is an optimal length for the lag-phase. Along the horizontal axis we vary the parameter d R that determines how fast the regulator is phosphorylated. The dependence of the fitness on this parameter shows two phases. For low values, corresponding to long lag-phases the fitness does not depend on the parameter. For higher values, there is an optimum d R for the competitor. The inset shows a detailed view of the optimum. In this particular example, the parameter d R evolved close to the otimal value. b The same data but time to take up N 1 and the fitness plotted as a function of the switching delay. All data from in these plots was obtained by taking a single evolved solution and varying the parameter d R . All simulations here show an evolved solution and the incumbent against which this solution evolved
