A Comparative Analysis of NSGA-II and NSGA-III for Autoscaling Parameter Sweep Experiments in the Cloud

Table 7

Hypervolume (average hypervolume value) and coverage (average coverage value) of the Pareto sets obtained by each autoscaler during the first autoscaling stage (first hour), for each studied application and size. For hypervolume measure, higher values represent better results. For coverage measure, lower values represent better results.
