Abstract

In this paper, we introduce a simple undirected graph based on a binary relation by using the
notion of right neighborhood and minimal approximation space. Also, we investigate the lower
approximation and the upper approximation of a subgraph to compute the rough subgraph. Finally, we
will make a reduction of an information system and compute the core of knowledge by using a minimal
approximation space and a graph theory.
