Figure 6

Estimated parameter sets for Model 2 The parameter sets are estimated by using GA (A) and PSO (B), and in each figure, the histograms of parameter sets with and without DE constraints (right and left sides, respectively) are shown. The bin of the histogram indicates the fraction of the number of parameters within a range (1.0 for all parameters) to the total number of trial successes (200 for all cases) (see details in Methods).
