Summary of the statistical test results from each metric (respectively, $IHrd$⁠, $Iε+$⁠, $IIGD$⁠) per scenario (rows: $FEmax$⁠; columns: $M$⁠). The given $AutoMOEA+$ algorithm may have been considered better than (+), equivalent to (=), or worse than (-) the best-performing MOEA(s) for the given scenario. MOEAs that match or outperform an $AutoMOEA+$ according to all metrics are indicated in parentheses.
