首先给出了三类回归数的定义,应用放缩法详细讨论了三类回归数的存在范围;然后根据每类回归数的性质和特点,利用搜索法和剪枝函数设计了相应的快速求解算法;最后利用数学软件编程求出了三类回归数的所有解.
Firstly the existence ranges of three kinds of regression numbers are investigated in detail by scaling after their definitions are given. Based on the properties and characteristics of each kind of regression numbers,the corresponding rapid solution algorithms for the determination of three kinds of regression numbers are designed by searching method and pruning function. All solutions to the three kinds of regression numbers are worked out by mathematic software.
