摘要
指出求信息系统的最简规则是一个二维极简化的问题,将行分辩且列组合具有最大强度的属性值定义为粒极值,以其逻辑关联的程度逐级进行粒运算,得最简粒(规则)解集.从理论上统一了求解信息系统的算法并用各类实例以证明.
Pointing out that method for solving the information system is a minimization problem of two-dimensional,attribute value that the dfiniting on row and compositing on column intensity is maxima was defined as the limiting value of granular,logic operation of granular comput on the preferred degree of logic independence with it stage by stage,finally minimization granular（rules） sets is got.Unifies the algorithm soluting for the nformation system on theory and the experiments show that it is efficienal.
