Researchers have introduced SPEA2$^+$, an enhanced version of the SPEA2 algorithm designed for multi-objective optimization problems. This new variant addresses limitations in the original SPEA2's ability to maintain diversity among dominated solutions, which was identified through theoretical runtime analysis. SPEA2$^+$ incorporates all pairwise distances in its fitness assignment, improving its efficiency on complex benchmark problems like OneTrapZeroTrap and matching SPEA2's performance on simpler tasks.
