Fuzzy rough sets with a fuzzy ideal
Abstract In this paper, we defined the fuzzy upper, fuzzy lower, and fuzzy boundary sets of a rough fuzzy set λ in a fuzzy approximation space (X,R). Based on λ and R, we introduced the fuzzy ideal approximation interior operator intlambda R and the fuzzy ideal approximation closure operator cl λ R...
