Generalization of Rough Set Theory Using a Finite Number of a Finite d. g.s

Y. Y. Yousif, S. S. Obaid

Abstract: This paper is concerned with introducing and studying the new approximation operators based on a finite family of d. g. 's which are the core concept in this paper. In addition, we study generalization of some Pawlak's concepts and we offer generalize the definition of accuracy measure of approximations by using a finite family of d. g. 's.

Keywords: Digraph, Mixed degree set, n-lower approximation, n-upper approximation and n-accuracy measure
