Comparison of performances between ACO-ME and hill-climbing (with and without Steepest Descent, SD) after a fixed run time of 1 minute on datasets of 55 (a) and 500 (b) taxa. A paired Wilcoxon test indicates that ACO-ME performances are significantly better (p-value = 3.92e-2 for 55 taxa dataset, and p-value = 6.821e-4 for 500 taxa dataset) than those of hill-climbing with SD, but significantly worst (p-value = 4.71e-3 for 55 taxa dataset, and p-value = 4.53e-4 for 500 taxa dataset) than those of hill-climbing without SD.
