In recent years, set-valued optimization make much progress. In Chapter 5, based on Clarke tangent cone, we establish epiderivative of a class of set-valued maps and its properties. And furthermore, sufficiency optimization conditions of set-valued optimization are also obtained.

在第5章中，针对近几年发展起来的集值优化，基于Clarke切锥利用Epigraph建立了一类集值映射的Epi-导数并讨论它的一些性质，同时给出集值优化的充分的最优性条件。

Generally, the set of temporal types that can be processed by a system and involved in lots of applications, meet totally ordered relation, and the set of TFDs with a totally ordered set of temporal types is closely related to the Armstrong axioms of traditional functional dependencies.

一般来说，系统所能处理的和相当多的应用所涉及到的时态类型集满足全序关系，并且具有全序时态类型集的TFD集的推导规则与传统函数依赖的Armstrong公理有着紧密的联系。

For a universal set, the set of all elements in the set that are not in a specified subset.

The vertex set of the complete graph Tof a graph G is the union of the vertex set of G and the edge set of G,two elements are adjacent in T if they are neighbour elements in G.

全图T是以V和E为顶点集，当T的两个顶点在G中是邻元素时，它们邻接。

Uniqueness of solution for generalized variational inequality related to strongly monotone Lipschitz mapping is shown. A sufficient condition is presented on the connectedness of solution set for the weak vector variational inequality on which the mapping is from a topological vector space X to L , where Y is also a topological vector space. The result is derived by discussing the properties of set-valued mapping induced by solution set of a scalar variational inequality related to the weak vector variational inequality.

利用拓扑向量空间到连续线性映射空间L的映射的弱向量变分不等式和与之相关的标量型变分不等式解集的关系，得到标量型变分不等式解集所表征的集值映射的特性和弱向量变分不等式解集的连通性条件。

Thirdly, basing on the content of feature selection related in Weka which is an open source data mining tool, we propose a new feature selection algorithm based on rough set theory, which viewed the set of core features as the initial set, and define a symmetrical uncertainty measurement method as features correlation evaluating criterion.

进而，在剖析数据挖掘开源工具Weka系统中的属性选择实现的相关内容的基础之上，提出了一种新的属性选择算法，该算法以粗糙集合理论中的核集作为属性选择的初始集合，以对称不确定性作为属性评价方法，综合考虑了属性与类之间和属性与属性之间的相关性。

In the early 20th century onwards, to meet the needs of the Chinese market, WODEN company entry into the Chinese market have been set up in Kunshan, Wharton Technology Co., Ltd. is a major response to the Pearl River Delta economic circle, set at home and abroad in trade and industry, special technical services and Lubricants Products Sales of integrated joint-venture company is also Woden in mainland China's second subsidiary, and in Guangdong to set up large-scale deployment of storage and logistics base.

If the reference count reaches zero, the element is removed from the set: If drop finds its element in the set, it decrements the element's reference count and the number of elements in the set.

如果该元素的引用计数器变为0，则从集合中删除该元素。+如果drop函数在集合中发现了其参数所指向的元素，便将该元素的引用计数和集合元素数减一。
