| 摘 要： | 受在感知过程中抓住主要特征的启发,结合复合材料层压结构优化问题的特点,借鉴遗传算法、蚁群算法等模拟进化优化算法的流程,提出1种"特征提取"的优化算法。根据目标函数值f(→Xj)(j=1,2,…m)的大小,对相应的m个设计变量向量→Xj=(x1,j,x2,j,…,xi,j,xn,j)(j=1,2,…m)进行排序;在一定的"背景噪声"S下,根据"特征提取"指示向量P提取群组中较优方案的共同特征,生成m个新的设计变量→X′j。算例验证表明,所提出的算法是有效的。 |

| Abstract: | A ＂characteristic extraction＂ optimum algorithm was proposed by the inspiration of the main character during the perception process,combining the characteristics for the composite laminate structure optimum,referencing the simulated evolutionary optimum algorithm process,such as GA（genetic algorithm）,ACO（ant colony algorithm）,et..The design variable vectors →Xj=（x1,j,x2,j …,xi,j,x n,j）（j=1,2,… m） were ranked according to the value of the object→ f（X j）（j=1,2,… m）.Based on the ＂background noise＂,the new design variable vectors →X＇j（j=1,2,…m） were generated by extractiong the common characteristics of the better cocepts in the group according to the＂character extraction＂ designation vector.The numerical examples shows that the algorithm is effective. |
