SPEA2+ algorithm enhances multi-objective optimization with improved diversity

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.

    SPEA2$^+$: Improved Density Estimation in SPEA2 with Provable Runtime Guarantees

    The Strength Pareto Evolutionary Algorithm 2 (SPEA2) is a popular and prominent evolutionary algorithm for solving multi-objective optimisation problems. Despite its popularity, theoretical analyses of SPEA2 have only appeared recently. Moreover, these analyses focus exclusively …
