Comparison of stochastic and deterministic simulation outputs. Comparison of stochastic and deterministic simulation outputs. The stochastic simulations required too much computational time for it to be practical to sample the parameter space very densely. Since we have used only the mean values from the stochastic simulations, we explored the possibility of using deterministic simulations, which require a tiny fraction of the stochastic simulation time, to increase our sampling of the parameter space. The plot shows the average number of mRNA transcripts generated by the two methods, stochastic and deterministic. The straight diagonal line indicates a good match, and in fact the two methods differ by less than one percent in most cases. Parameter values are the same as those used in Figure 2A.
