SOME ITERATIVE ALGORITHMS OF THE BEST APPROXIMATION BY SEGMENTS AND THEIR CONVERGENCE
最优分段逼近的几个迭代算法及其收敛性

The author has solved some basic theoretical problems of several kinds of the best approximations by segments in1].In this paper,some iterative algorithms of the best approximation by segments are presented and their convergence is proved.All these algorithms can be easily implemented in computer.
