This paper presents an outlier detection method that is based on a Variable Precision
Rough Set Model (VPRSM). This method generalizes the standard set inclusion relation …

The correlation of rough set theory with topology has been a captivating field of research
since the inception of this relatively new theory. However, there has not been much study …

The relationships between T-rough sets and covering based rough sets are investigated,
and two kinds of generated methods of rough approximation operators from existing rough …

With the popularization of higher education, the scale of urban higher education continues to
expand, and the contradiction between the supply and demand of educational resources …

Pawlak firstly proposed rough set theory as a new way to solve imprecision, inconsistent and
incomplete problems in [14]. The core of rough set theory is a pair of lower and upper …

Rough sets and soft sets are important tools to deal with uncertainties. In this paper, we
apply rough soft set theory to BCK-algebras. The lower and upper rough soft BCK-algebras …

In this paper, the notion of soft rough BCK-algebras is introduced, which is an extended
notion of subalgebras in BCK-algebras. Moreover, in order to illustrate the roughness in …

In this paper, we investigate the relationship among rough sets, soft sets and rings. The
concept of soft rough rings (ideals) of rings is introduced, which is an extended concept of …

Molodtsov introduced the concept of soft set as a new mathematical tool for dealing with
uncertainties. Recently, Cagman and Enginoglu [16] provided new definitions and …
