The experiment collected 6 * 6 * 30 = 1080 observations, 23 out of whom are invalid. For function f15, the DLHS got 2 infeasible solutions. For function f17, the HS got 4 infeasible solutions and the IHS 5, the HSw 3, the DLHS 1, the SGHS 5, and the NSHS 3, respectively. The bold represents the significant best.
