Statistical significance of the difference in performance between the methods.

ANOVA P = 3.05 × 10-5
GP vs. SVM-K1 P = 0.0001	GP vs. SVM-K2 P = 0.3107	GP vs. SVM-K3 P = 0.0008	GP vs. MP P = 0.0009	GP vs. RF P = 0.0103

First line shows ANOVA test on the 6 samples of solutions found by each method, while second line depicts pairwise 2-tailed Student t-tests comparing GP with each other method.
