ABSTRACT
Metaheuristic algorithms are well-known optimization tools which have been employed for solving a wide range of optimization problems. Several extensions of differential evolution have been adopted in solving constrained and nonconstrained multiobjective optimization problems, but in this study, the third version of generalized differential evolution (GDE) is used for solving practical engineering problems. GDE3 metaheuristic modifies the selection process of the basic differential evolution and extends DE/rand/1/bin strategy in solving practical applications. The performance of the metaheuristic is investigated through engineering design optimization problems and the results are reported. The comparison of the numerical results with those of other metaheuristic techniques demonstrates the promising performance of the algorithm as a robust optimization tool for practical purposes.

fig4: Schematic of the tension/compression spring design problem.

Mentions: The tension/compression spring problem is designed to minimize the weight of the spring subjecting it to some constraints such as shear stress, minimum deflection, outside diameter limits, and surge frequency. The design variables are the number of active coils P, the diameter of the mean coil D, and the diameter of the wire d. Figure 4 shows the tension/compression spring design.
