| 摘 要： | 遗传算法作为一种比较成熟的智能算法,因其具有全局搜索能力和并行性得以在翼型气动优化中广范应用.本文在编码方式、种群初始化和遗传算子等方面对标准遗传算法进行了改进.其中,DNA的编码方式增加信息的丰富性;拉丁超立方抽样初始化使种群分布相对均匀;插入、删除、倒位等算子增加种群的多样性,加快收敛;感染算子加速种群摆脱停滞或早...

| Abstract: | Genetic algorithm,which is a mature aptitude algorithm,has been widely applied to airfoil design.In this paper,the standard genetic algorithm is improved by encoding genetic operators and initialization,So that the DNA encoding includes more information;the Latin hypercube sampling distribution of the initialization population is more reasonable;insertion,deletion and inversion operators increase the diversity of the population to accelerate convergence;infection operator gets rid of stagnation or premature... |
