Abstract

Over the last decades, studies concerning efficient metaheuristics has risen considerably among researchers in combinatorial optimization. Hybrid metaheuristics, in particular, has found the best results for many optimization problems. The main goal of this project is to develop and improve new alternatives for the hybrid Clustering Search method (CS), making it flexible, robust and efficient both in terms of the quality of the solutions and the computational effort. We intend to research this project through three different sub-research lines which include: the development of a new way of detecting promising areas, the designing of a multiobjective CS and the exploration of ways to parallelize the CS. These proposed methods are applied to resolve different optimization problems with many practical applications. The computational tests will use cases available in the literature and if possible, real cases using data from companies in the region. (AU)
