Table 2. Time complexities of the methods.
| Method | Time complexity |
|---|---|
| ILP | O(|S|n) |
| GA | O(maxGeneration *n*Pg ) |
| KS | O(n*k*Itermax) |
| SGGA | O(|S|)+O(maxGeneration *n*Pg ) |
Note:
k is denotes the number of cluster and Itermax is equal to maximum iteration in the KS method.
