It is evident that DGSO performs better than the other reported algorithms especially in case of the high dimension functions.
Next we compare the convergence speed between the DGSO and the other four algorithms including GSO, OGSO, RGSO, and RDGSO.
For convenience, two algorithms DGSO that used the diversity-guided operator and OGSO that is the opposition-based algorithm without diversity-guided operator are compared.
The proposed DGSO is also compared with some other well-known evolutionary algorithms  based on these benchmark functions.
Table 7 describes the comparison results of DGSO and some other algorithms when D = 100.
