因此，整型问题的约束放松并不一定会改进解决方案，因为可行域是离散的，而不是连续的。
Thus, a relaxation of the constraint of an integer problem does not necessarily improve the solution, because the feasible region is discrete and not continuous.
针对非视距环境下多站定位方法需要资源量大、成本高且定位精度受非视距传播影响大等问题，本文提出了单站定位的伪目标动态可行域约束法。
A location method aiming at suppressing NLOS errors in cellular networks using single observer is proposed, which is named by pseudo-target dynamic feasible region constraint method.
由于多层复形法全部优化过程都是在可行域内进行，所以得出的优化结果必然满足约束条件。
Due to multilayer complex method of the whole optimization procedure at feasible zone, the optimization can meet the condition of constraint.
计算结果表明该文提出的约束复合形法在非凸可行域上的修正算法是可行的。
The computation results show that the method of modifier algorithm of constrained complex method in concave feasible fields, proposed in this paper, is effective.
运输问题存在“多反而少”现象，这是由于在松约束模型中放宽了约束条件，使得可行域变大，产生了新的最优解。
The Transportation Problem exists"more-for-less"paradox, which because the loose-constrained model has broadened the restriction, enlarged the feasible area, and bring new optimal solution.
