In this chapter, firstly, the definition of rough semigroups is given afresh. Then based on rough groups, rough subgroups, rough cosets, rough invariant subgroups, some properties of rough subgroups and rough invariant subgroups and the concept of rough quotient groups are introduced. Finally, based on some concepts of homomorphism and isomorphism of rough groups, basic homomorphism theorem and isomorphism theorem of rough groups are put forward and proved.

To gain an ideal algorithm, based on the theories of rough set and granular computing, the basic algorithms of indiscernibility relation and computing positive region were designed, in which dynamic SQL was used to directly get the sorted object sets so that the sort algorithm was left out.

摘 要：为获取高效算法，结合Rough集和粒计算理论，基于知识颗粒设计出获取等价类的算法及计算正区域的等价算法，使用动态SQL语句直接获取已排序的对象集，省略类似算法必需的排序算法，降低了实现的复杂度。
