RT info:eu-repo/semantics/article T1 A direct search algorithm for global optimization A1 Baeyens Lázaro, Enrique A1 Herreros López, Alberto A1 Perán, José K1 Global optimization K1 Direct search methods K1 Search space transformation K1 33 Ciencias Tecnológicas K1 12 Matemáticas AB A direct search algorithm is proposed for minimizing an arbitrary real valued function. The algorithm uses a new function transformation and three simplex-based operations. The function transformation provides global exploration features, while the simplex-based operations guarantees the termination of the algorithm and provides global convergence to a stationary point if the cost function is differentiable and its gradient is Lipschitz continuous. The algorithm’s performance has been extensively tested using benchmark functions and compared to some well-known global optimization algorithms. The results of the computational study show that the algorithm combines both simplicity and efficiency and is competitive with the heuristics-based strategies presently used for global optimization.
