| 摘 要： | 在实现标准基因算法的基础上，用ＧＡ－Ｓｉｍｐｌｅｘ代替ＧＡｓ中的交叉和变异构成一种新算法，详细探讨了以何种方式在群体中选取个体进行ＧＡ－Ｓｉｍｐｌｅｘ操作，找到了一种较理想的方式，并从基因操作的内在机制进行了分析．进而构造了一种混合式方法，使计算速度和效果大为改善．然后详细研究了在ＧＡｓ的迭代循环中如何适时进行区域收缩．最后引入适值调整，找到了一种循环次数少、计算时间短、求解结果令人满意的ＧＡｓ算法

| Abstract: | On the basis of the realization of canonical genetic algorithms (GAs) and by substituting the crossover and mutation in GAs with GA -Simplex,a new algorithm is formed. How to choose individuals in the colony for GA -Simplex operation is discussed and an appropriate method has been found and analyzed from the inner mechanism of gene operation. A hybrid method for GA -Simplex operation to improve the computation speed and to give better results is developed. The method of carrying out regional contraction in due time during the iteration of GAs is investigated and the fitness scale is introduced. A GAs with satisfactory calculation results and less times of iteration as well as shorter calculating time is found. |
