(a) A plot of σ² vs γ₆ obtained in wSSA runs of reaction 21 using the algorithm in Fig. 1. Here we estimate p(0,ε_Gbg;20), where ε_Gbg is the set of all states x in which the population of G_bg is 50. Each vertical bar shows the estimated mean and one standard deviation of σ² at that γ₆ value as found in four n=10⁸ runs. (b) A plot of σ² vs ${\gamma }_6^{\text{max}}$ obtained from using the algorithm in Fig. 3. Each vertical bar was obtained from four n=10⁸ runs.
