说明：  属性约简是粗糙集理论中的一个重要内容,其核心任务是得到属性集的核。本文提出了一种基于二进制运算 的属性核求解算法,该算法简单直观且易于实现。我们通过设计C语言程序验证了算法的有效性。
(Attribute reduction is considered one of the most important contents of the rough set theory,and core obtai- ning plays an essential role in attribute reduction.This paper proposes an algorithm for finding the core based on binary op- eration,and the algorithm is simple and easy-to-be-implemented.The validity of the algorithm is proved by C programming. )
