摘要
针对决策系统核属性的计算问题,提出一种基于决策系统的求核算法。该算法不需要建立分辨矩阵,具有较低的时间复杂度和空间复杂度。
The problem of calculating the core attributes of a decision system is studied.An algorithm to compute core of decision system based on discernibility list is presented.This algorithm has no demand on the construction of discernible matrix,and has much less time and space complexities.
