Table 5 The comparison of time complexity of different rough set measures
From: A data fusion method in wireless sensor network based on belief structure
| Measure | MGRS based on belief structure | MGRS | Covering rough set | Traditional rough set |
|---|---|---|---|---|
| Time complexity | \(O(m*n)\) | \(O(n^2)\) | \(O(m^2*n^2)\) | \(O(m*n^2)\) |
