一种新的集合表示方法(刻划函数方法)及其运算

A New set-Representing Method (Depicting Function Method) and Its Operations

本文提出了一种新的集合表示方法即刻划函数方法,并且讨论了在该表示方法下的集合运算.该方法不同于特征函数法和线性表表示方法.该方法把集合表示成刻划数,刻划数唯一刻划了集合的本质特征,使得集合运算转化为简单的数值运算,运算方便,节省空间.

In this paper, a new set-representing method, depicting function method, is presented, and set-operations under the method is discussed. This method is different from the feature Function and Linear list representing method. This method maps set into depicting number which depicts nature feature of the set, changes set-opera t ions into simple numerical operations, and savcs the storage space.
