Simulation results of the Congress on Evolutionary Computation constraint optimization standard function indicate that the ε- onstraint maintenance optimization method is effective in solving the multi-constraint surrogate model optimization problem compared with the existing methods. The results for the solid rocket motor rear wing pillar charge design show that the algorithm has the potential to be applied to complex engineering problems.]]> 2025/10/8 0:00:00 MA Shuaichao, WU Zeping, YANG Jiawei, GAO Jingwei 5true 2025/10/8 0:00:00 ZHANG Jin, WANG Kemao, YAN Bing, WANG Liyao 4true 2025/10/8 0:00:00 LIN Yujing, LIU Weidong, WEI Feng, YANG Rui, YU Jiangfei 3true 2025/10/8 0:00:00 DONG Changlin, ZHOU Shiming, LI Daokui 2true 2025/10/8 0:00:00 ZHOU Danfeng, ZHU Pengxiang, TAN Yiqiu, WANG Lianchun, LI Jie, CHEN Qiang 1true
