Dissertação (Mestrado em Modelagem e Otimização) - Universidade Federal de Goiás, Catalão, 2018.http://repositorio.ufcat.edu.br/tede/handle/tede/9204The formulation and solution of optimization problems configures a research line of great applicability, with emphasis in engineering systems design. Traditionally, the solution of these problems can be found by considering classical and metaheuristics methods. As an example of this last class we can cite a recent bio-inspired technique, the Whale Optimization Algorithm (WOA). This evolutive strategy consists in generating candidates to solve optimization problems through simulation of movements of humpback whales in search for food. However, this recent optimization technique requires new studies in order to improve its performance in problems more complex. Therefore, the present contribution aims to propose the Adaptive Whale Optimization Algorithm (AWOA), that consists in updating the internal parameters of WOA considering the concept of convergence rate and a cognitive social operator as alternative to generate potential candidates. The methodology is applied to mathematical problems and to engineering systems design. The results obtained demonstrate that the AWOA presented good performance in relation to WOA, but without increasing considerably the computational cost when compared to other evolutionary strategies.application/pdfAcesso AbertoOtimizaçãoSistemas bio-inspiradosWhale Optimization AlgorithmProblemas de sistemas de engenhariaOptimizationBio-inspired systemsWhale Optimization AlgorithmEngineering systems designTEORIA DA COMPUTACAO::ANALISE DE ALGORITMOS E COMPLEXIDADE DE COMPUTACAODissertação
