Different engineering problem comparison result.

Problems	Aim	Result
Tension/ compression spring design problem	Minimizing the weight of tension/ compression spring is the goal of this design problem	WOA had better performance over PSO and GSA on average, and both PSO and GSA required more function evaluation than WOA [5]
Welded beam design problem	Minimizing the fabrication cost of the welded beam is the objective	WOA outperformed over PSO and GSA on average and required the least number of function evaluations to find the best optimal solution
Pressure vessel design	The objective is to minimize the total cost of a cylindrical vessel	WOA performed better compared to PSO and GSA on average and the required of a number of evaluation function [5]
15-bar truss design problem	Minimizing the weight of the 15-bar truss is the goal of this problem	WOA had similar performance, which would find a similar structure with other algorithms. WOA had the second rank for the number of the evaluation function
