有界变量 meaning in English

bound variable
bounded variable

A simple method of linear programming for bounded variables
有界变量线性规划的一种简易解法
The method proposed in this paper is a generalization of basis deficiency - allowing variation of the simplex method to linear programming problems with bound constraints
为克服单纯形算法中退化现象带来的困扰,本文在文[ 1 ]的基础上进一步提出亏基有界变量单纯形算法,并证明了算法的收敛性
One is based on the bounded simplex method . at first , nonlinear equations was transferred to linear equations whose feasible region contained all solutions in the given interval vector , then the bounded simplex method was used to determine whether the feasible region was empty or not
有界变量单纯形法：首先将非线性问题转化为带约束条件的线性规划问题，该线性规划的可行域包含了所给区间向量范围内的所有解，然后使用有界变量的单纯形法判断可行域是否为空。
