摘要
传统多目标优化算法因参考点分布僵化、环境适应性弱与种群多样性衰减,常导致解集分布失衡且收敛效率不佳.为此,本文提出融合自适应更新参考点策略和种群预测机制的多目标优化算法.首先,设计一种精英基因引导生殖交叉算子,通过干扰交换和继承三重机制增强全局搜索与多样性;其次,建立种群预测机制,结合正则化回归与边界扰动预测新解,经误差修正实现历史信息与新种群的动态融合;然后,提出自适应更新参考点策略,动态剔除无效点并生成新点,优化高维目标空间覆盖;最后,给出基于自适应更新参考点策略和预测种群机制的多目标优化算法的完整框架.实验结果表明,该算法在一系列测试问题和实际铝电解工艺参数优化案例中表现优异.
Traditional multi-objective optimization algorithms often suffer from rigid reference point distribution,weak environmental adaptability,and population diversity degradation,leading to imbalanced solution set distribution and low convergence efficiency.This paper proposes multi-objective optimization with adaptive reference-point updates and pop-ulation prediction.Firstly,an elite gene-guided reproductive crossover operator is designed to enhance global search and diversity through a triple mechanism of interference,exchange,and inheritance.Secondly,a population prediction inte-grates regularized regression with boundary perturbation to forecast new solutions,achieving dynamic fusion of historical information and new populations via error correction.Thirdly,an adaptive reference point update strategy dynamically eliminates invalid points and generates new ones to improve coverage in high-dimensional objective spaces.Finally,a complete algorithmic framework is established based on these strategies.Experimental results demonstrate the algorithm’s superior performance on benchmark test problems and a real-world aluminum electrolysis process parameter optimization case.
