interval of convergence

On the collectivism and distribution of power series in its extremity section
关于幂级数在收敛区间端点的敛散性问题
A set of calculation softwares was programmed by simulated annealing algorithm . these softwares can find the best solution without being given initial values but region of convergence , and have a lot of advantages such as fast convergence , good stability and high accuracy
根据模拟退火算法编制的一系列计算软件能在大面积内快速搜索，无须给定初始值，只要给定收敛区间，就能对可疑的点进行逐次逼近，直至搜索到一组最佳的薄膜参数值。
In chapter 2 , a sort of genetic algorithm based on estimation range is presented . by the means of probability analysis , the convergence area of the optimal result can be estimated . in this way , the search range can be shrinked > the search precision can be improved and the quality of result can be ameliorated
本文针对优化设计中的智能方法进行了研究，在本文的第2章，提出了一种基于区间估计的遗传算法，应用概率分析，通过对最优解的收敛区间进行估计，缩小了搜索范围，提高了搜索精度，最优解的质量有所改善。
