“…To investigate the general behavior of each objective function, we choose four initial actuator location sets as i) [1.66, 3.33. 5.00, 6.67, 8.33], ii) [1.00, 3.00, 5.00, 7.00, 9.00], iii) [3.00, 4.00, 5.00, 6.00, 7.00], and iv) [2.00, 3.00, 4.00, 5.00, 6.00] and carry out the optimization. The corresponding local minima are given in Table 5.…”
