Researchers have introduced SPEA2$^+$, an enhanced version of the Strength Pareto Evolutionary Algorithm 2 (SPEA2) designed for multi-objective optimization problems. The new variant addresses limitations in SPEA2's density estimation for dominated solutions, which previously hindered its efficiency on certain benchmarks. SPEA2$^+$ utilizes all pairwise distances for fitness assignment, improving its performance and achieving comparable guarantees to other leading algorithms like NSGA-II and SMS-EMOA. AI
