1.
The algorithm introduces a novel optimization technique combining with border sets and generator representation.
该算法引入了一个全新的优化方法,将边界集和频繁产生集结合起来。


2.
Firstly,this article gives a sufficient and necessary condition when a set is a closed one in a topological space,than gets a closure in a topological space and a closed set whose closure is the smallest of all closed sets that contain it when the border set must be a closed one.
本文首先给出了拓扑空间中的一个集合为闭集的充要条件,从而进一步得到拓扑空间中的一个集合的闭包和边界集必为闭集并且它的闭包是包含着这个集合的最小的闭集。
