  • Abstract
    In the covering-based generalized rough set setting, lower and upper approximation operations generated by a covering do not satisfy some of common properties of classical lower and upper approximation operations. In this paper we investigate conditions for a covering under which these properties hold for the fourth type of covering-based lower and upper approximation operations.
