Rank sum difference (in parentheses) between the given MOEA and the lowest ranked (⁠$FEmax=40000$⁠). MOEAs in boldface present rank sums statistically significantly lower than the others according to Friedman's test. For brevity, only the six best-performing MOEAs from each scenario are shown, and $AutoMOEA+$$〈5,40k,Iε+〉$ is abbreviated as $Auto-ε$⁠.
