| 摘 要： | 基本遗传算法在求解大规模多目标优化问题时会出现早熟和搜索效率低等问题。针对这些问题,对基本遗传算法引入了邻域操作、自适应策略和混沌优化等多种改进策略,研究设计了一种有机结合各种改进策略的改进遗传算法流程。应用实例的仿真试验表明改进算法可行,且在求解大规模多目标优化问题时较基本遗传算法具有精度和速度优势。

| Abstract: | Basic genetic algorithm has been confronted with several problems such as premature and low-search-speed when it is applied to solve military multi-object optimizing problems.To avoid these problems,some methods including adjacent-domain operations,adaptability and chaos have been taken into consideration in this paper to improve the capability of the algorithm.Furthermore,the paper designs an improved algorithmic flow structure which organically combined all the above methods.The simulation(results) show that the improved algorithm is more reliable and more accurate than the basic algorithm in(solving) multi-object optimizing problems. |
