(c) Figure 4: Damage case 3 – CCCC plate. (a) Element mesh numbers, (b) damage Index, and (c) Comparison of   4,8 H before and after damage. Tab. 3 shows the fitness values for all cases in some iteration pints. In this table, the performance of WHO algorithm is better from the earliest stage of the search, while the other two algorithms make progress but in a much slower manner. Fig. 6 presents the damage index convergence in the first case, comparing the performance of the three algorithms. This figure shows that all algorithms are efficient for this variable; as shown in Tab. 4, the three algorithms converge toward the actual damage severity, but the WHO algorithm accuracy is higher.
