摘要：This Paper deals with a new type of Reduct in the object-oriented rough set model which is called dynamic reduct. In the object–oriented rough set models, objects are treated as instances of classes, and illustrate structural hierarchies among objects based on is-a relationship and has-a relationship[6]. In this paper, we propose dynamic reduct and the notation of core according to the dynamic reduct in the object-oriented rough set models. It describes various formal definitions of core and discusses some properties about dynamic core in the object-oriented rough set models.
