| Abstract: | Variation S-rough sets were puts forward. The mathematical structure of one direction variation S-rough sets and two direction variation S-rough sets were given; forward dual theorems and principle of variation-dual of S-rough sets were also put forward. Variation S-rough sets is a new research direction of S-rough sets. |
