Abstract
Covering-based rough set (CRS) is a meaningful and important generalization of Pawlak´s rough set theory. The primary goal of this paper is to extend the formal study to partial covering (PCov) in terms of the global granular computing model (global/2nd GrC model). The main focus is to investigate the “best” approximations, where “best” was used by Pawlak in his 1982 paper. The study includes a comparison with many existing theories.
