We extend RDEx-CSOP with 3 changes that target stagnation & late-stage variance, plus minor parameter tuning. The second scale factor in the standard branch is sampled independently from a truncated Cauchy. A small feasible-only JADE-style archive (|A|_max = 50) is added & sampled with probability |A|/(|A|+|P|). Per-individual stagnation counter triggers, after 180 no-improvement generations, three local overrides on standard branch: pull toward the global best, lift the archive sampling floor to 0.65, & saturate CR to 0.95 when population success rate is below 0.10. The exploitation biased branch & every other RDEx component are left untouched. On CEC CSOP suite (D=30, 25 runs), RDEx-CASK is competitive with RDEx, UDE-III, & CL-SRDE in feasibility-aware quality & improves time-to-target on most problems.
翻译:我们对RDEx-CSOP进行了三项改进,旨在解决停滞问题与后期方差衰减,并辅以微小的参数调整。标准分支中的第二缩放因子从截断柯西分布中独立采样。引入一个仅包含可行解的、规模较小的JADE风格存档(|A|_max = 50),并以概率|A|/(|A|+|P|)进行采样。当个体经过连续180代无改进时,个体级停滞计数器会触发对标准分支的三项局部覆盖:向全局最优解牵引、将存档采样下限提升至0.65、以及在种群成功率低于0.10时将交叉概率CR饱和至0.95。利用偏向分支及其他所有RDEx组件均保持不变。在CEC CSOP测试套件上(D=30,25次运行),RDEx-CASK在可行性感知质量指标上与RDEx、UDE-III及CL-SRDE具有竞争力,并在大多数问题上缩短了达到目标时间。
