摘要
提出了一种在低能电子衍射 ( LEED)结构分析中自动搜寻最佳模型的优化方法——遗传算法和张量 LEED相结合的联合方法 .这种新方法的特点是能在全部参数变化范围内自动搜寻 ,避免了陷入“局域”优化模型的困难中 .本文给出了这一方法的应用实例 。
A new optimization method was presented in LEED \%I\|V\% curve analysis applying genetic algorithms (GAs) in Tensor LEED. It can avoid the danger in identifying an incorrect structure because a local rather than a global minimum in the R\|factor was found. A sample of the method was given. The potential of GAs in the future and other fields were also described.
