“…We examine the performance of FDD-EA-DH on the DTLZ [38] and WFG [39] test suite, with the number of objectives M being set to 3, 5, or 10, and the numbers of decision variables D being set to 20. The maximum number of fitness evaluations F E max for 20-dimensional test instances is set to 219+120 (219 is the number of raw data in each client and 120 is the number of allowed new query points throughout the optimization process), respectively, which is the same as the setting of the number of initially sampled solutions in [9], [37], i.e., 11 • D − 1. The number of queried solutions µ is set to 5.…”
