Bland方法的改进

Improvement on the Bland Method

用单纯形方法解线性规划问题过程中出现退化情况时 ,可能出现循环现象 ,1976年 ,Bland提出一种避免循环的方法 .本文对其做了一点改进 ,使其理论上比Bland方法迭代次数少 。

Recurring phenomenon probably occurs when we use simplex method to solve linear programming problem and meet degeneration.In 1976,Bland came up with a method to avoid recurrence.This article made a little improvement on it ,making it less repeated than Bland method in theory and more easily realized in computer.
