To compare the performances of various EAs, statistical measures like best, mean, standard deviation of results and average computation time, over 20 independent trials are considered.
In Figure 4a, it can be seen that the best evolved standard deviation of the unregulated system is 10.4 molecules per cell; the minimum standard deviation of the system with negative regulation is 8.2 molecules per cell.
The statistical performances of the designed controllers such as best, mean, standard deviations of IAE and average functional evaluations for 20 independent trials.
In a coastal defense study three sea level rise scenarios were considered, namely: the 'policy' scenario including sea level after global implementation of climate change mitigation policies; the 'anticipatory' scenario describing the best guess; and the 'unfavourable' scenario describing the best guess plus standard deviation (De Ronde and Vogel, 1988).
However, Sun and Mashima [29] correlation gives the best predictions with standard deviation of 13% for high mass flux only, but it over predicts measurements for low mass fluxes.
However, the Wan et al. method is best for estimating standard deviation under normal distribution.
Each criterion should have the best, average, and standard deviation results.
Of the six measured areole characteristics shown in Fig. 9, leaf rank actually correlates best with areole standard deviation (r = 0.59).
RSpredict had stable performance with the best mean 0.85 (standard deviation 0.16, respectively) in MCC, while the other methods' MCC values varied a lot and had means (standard deviations, respectively) ranging from 0.71 to 0.82 (0.24 to 0.28, respectively).
COPASI provides, in addition to the best parameter set, standard deviation of the parameter estimates assuming a maximum-likelihood statistics, which in effect expands a quadratic surface of the sum-of-squares fit criterion around the optimal fit.
