Implementation of the Electromagnetism-Like Algorithm with a Constraint-Handling Technique for Engineering Optimization Problems

This paper presents the implementation of a constraint-handling technique within the electromagnetism-like algorithm devised by Birbil and Fang, for solving real-world engineering design problems. A derivative-free elite-based descent search scheme is also included in the final stage of each iteration to accelerate convergence and improve accuracy. Numerical experiments with a set of engineering problems are carried out and a comparison with other stochastic methods is reported.
