Rough graph and its structure
Tong He · Journal of Shandong University · 2006
By combining the rough set theory with the traditional graph theory,the equal definition of classical graph is presented based on the idea of rough set theory.In general,the definition of rough graph is given.Furthermore,the matrix expression of rough graph and the rough characteristic analysis of rough graph are also given.Rough graph extends the results of classical graph theory.It is the graph that can be used to research uncertainty problems,and is also a new research tool to analyze the system rough characteristic.
