Rough set (RS) and generalized rough set theories utilize single relations to obtain approximations of sets on a given universe of discourse. In granular computation, this is called single granularity. This article first expands -fuzzified RSs established on fuzzy tolerance relation to -optimistic multi-granulation fuzzified RSs by using a set of tolerance fuzzy relations over a given universe. Moreover, several elementary measures are proposed in this framework. Its application in feature selection has been highlighted through experimental analysis.
