采用遗传基因算法实现切削数据的拟合，用数据库技术实现算法—将基因（ｇｅｎｅ）视为字段、染色体（ｃｈｒｏｍｏｓｏｍｅ）视为记录、种群（ｐｏｐｕｌａｔｉｏｎ）视为库，以数据库的基本操作替代遗传过程；解决了传统回归分析方法的不足，使回归过程简单、结果稳定、可靠，并为回归分析提供了一条新途径。 The genetic algorithm is used to fit the cutting data and the algorithms are implemented using database technology - the gene is treated as a field, the chromosome is considered as a record, the population is considered as a library, the database is replaced by a basic operation Genetic process; Solve the traditional regression analysis of the deficiencies, the regression process is simple, the result is stable and reliable, and provides a new way for regression analysis.
