摘要
关于粗糙集理论，Yun和Qiu(2011)提出了一个悬而未决的问题，即如何仅使用数据项近似的上、下算子来表征其邻域的条件，以形成数据的宇宙U的分区。问题的第一部分已经解决了Fan and Hu(2012)。本文用一种特殊而简单的方法解决了这一问题的另一部分，并取得了一些有意义的结果。
Further Discussion of the Problem about Conditions of Neighborhoods Forming a Partition
There is an open question regarding Rough Set theory propsosed by Yun and Qiu(2011), which are how to characterize the conditions for a neighborhood of a data item approximations to form a partition of the universe U of the data by using only their upper and lower operators. The first part of the question has been solved Fan and Hu(2012). In this paper, another part of the question is addressed by a special and simple method, and some significant results are obtained.
