The lower bound of the optimal value of the problem ( QP ) is determined by Lagrangian slack and projection subgradient method. 利用拉格朗日松弛和投影次梯度方法来确定问题(QP)最优值的下界。
We first provide a lower bound of its optimal value which can be used to solve the problem optimally by branch and bound method. 该文首先给出一个最优解值的下界估计,它可用于分枝定界法求最优解。
A new lower bound for the logarithmic mean value 对数平均的一个新下界
A lower bound on the change-of-variance sensitivity of the fitted value is given for a subclass of general M-estimators of linear regression, and the estimator in [ 1 ] corresponding to η c reaches this lower bound. 本文对线性回归GM-估计的一个子类,给出拟合值方差改变敏感度的一个下界,并说明〔1〕中相应于ηc的估计量达到此下界。
The amended algorithms reduce respectively the lower bound of the order of finite field and the initial query value inputted to multiplicatively approximate multiplicative black box. 分别降低了原算法中有限域阶的下界和乘法近似黑盒的询问初值。
