RDEx-MOP: Indicator-Guided Reconstructed Differential Evolution for Fixed-Budget Multiobjective Optimization
- 用指标引导选择,结合多种进化算子平衡探索与利用。
- 在CEC 2025测试集上总分最高,平均排名领先所有对比算法。
- 适合追求快速收敛的多目标优化任务或竞赛应用。
在2025年CEC多目标优化挑战赛中,评价标准不仅包括最终的IGD值,还关注算法在固定评估预算下到达目标区域的速度。本文介绍用于该赛事有约束多目标优化赛道的重构差分进化算法RDEx-MOP。该方法融合基于指标的环境选择、保持种群多样性的帕累托候选集,以及互补的差分进化算子以实现探索与利用的平衡。我们使用官方发布的检查点轨迹和中位数目标U得分框架对RDEx-MOP进行评估。实验结果表明,该算法在所有公开对比算法中取得了最高总分和最佳平均排名,优于早期的RDEx基线版本。
原文摘要 · Abstract (English)
Multiobjective optimisation in the CEC 2025 MOP track is evaluated not only by final IGD values but also by how quickly an algorithm reaches the target region under a fixed evaluation budget. This report documents RDEx-MOP, the reconstructed differential evolution variant used in the IEEE CEC 2025 numerical optimisation competition (C06 special session) bound-constrained multiobjective track. RDEx-MOP integrates indicator-based environmental selection, a niche-maintained Pareto-candidate set, and complementary differential evolution operators for exploration and exploitation. We evaluate RDEx-MOP on the official CEC 2025 MOP benchmark using the released checkpoint traces and the median-target U-score framework. Experimental results show that RDEx-MOP achieves the highest total score and the best average rank among all released comparison algorithms, including the earlier RDEx baseline.
