提出了使用遗传程序设计采实现数据拟合的方法.用树的分层结构来进行个体染色体编码.给出了遗传操作算法框架以及选择、交叉、变异与种群评估算子的实现方法.通过计算实例表明遗传程序设计能有效地进行数据序列的复杂函数拟合,不需要对数据作深入的了解,在一定程度上实现了对数据变化规律的自动建模.%A method of data fitting was proposed using genetic programming.Multi-layer trees were used to code the each chromosome.The framework of genetic operation was suggested, and operators of selection, crossover, mutation and evaluation were described in detail.Finally, an example was given, and the results show that genetic programming can produce complex function by fitting data sequence.Because there is no need for deep understanding on the data sequence, genetic programming method can model the change law of data sequence automatically.
