Xie-Beni index decreases with the number of partitions increasing. It is difficult to choose the optimal partition of data when the number of clusters is large. From the point of view of the compactness and the separation of clustering, a novel clustering validity function is proposed, which is based on the improved Huber Г statistic combined with the separation of clustering.

针对此问题，分别考察改进的Hubert Г统计量和聚类分离度，导出一个新的基于数据几何结构的聚类有效性函数，使得它有惟一的最大值，函数值随聚类个数增大而递减的趋势并不影响最优聚类个数的判定。

A function f: V→{-1,1} defined on the vertices of a graph G is a signed total dominating function if the sum of its function values over any open neighborhood is at least one.

函数f：V→{-1，1}称为图G的符号全控制函数，如果对每一个开邻域集上的点的函数值的和都大于等于1。

And through the discussion of their localizations, a method is put forward to improve the optimal value of the objective function further by adjusting the LP's technique coefficients but not changing the optimal solution's structure, and the model is endowed with the inherent meanings of management innovation as well.

并在对两类线性优化逆问题自身局限性进行讨论的基础上，研究提出了在线性规划最优解结构不变的前提下，通过调整技术系数参数实现目标函数值进一步改善和优化的一种方法，且赋予了其企业管理创新的内在涵义。

This paper considers simultaneous or Pareto optimization between the scheduling cost of all the jobs and the degree of this disruption.

为了保证先来顾客的需求和工件本身错位量的要求，着重研究这种使先来顾客的总目标函数值与工件错位量之间达到平衡的问题，即重新排序问题的Pareto最优解问题。

In this paper,a new method for estimating the global optimum value in a global optimization problem is proposed .

给出了一种全局最优化问题的全局最优值估计的新方法；该方法通过求一个非线性方程的根使目标函数值逐步减小，因此该方法具有下降算法特征。
