Journal ArticleDOI
Improvements in genetic algorithms
TL;DR: The dynamic change of crossover and mutation probabilities, the space reduction and the global elitism during the evolution process show that great improvement can be achieved for all GA types.
Journal ArticleDOI
Electric distribution network multiobjective design using a problem-specific genetic algorithm
TL;DR: In this paper, a multiobjective approach for the design of electrical distribution networks is presented, where the objectives are defined as a monetary cost index (including installation cost and energy losses cost) and a system failure index.
Journal ArticleDOI
Inverse problem methodology and finite elements in the identification of cracks, sources, materials, and their geometry in inaccessible locations
TL;DR: Inverse problem methodology is extended, through the more difficult geometric differentiation of finite-element matrices, to identify the location, material, and value of unknown sources within an inaccessible region using exterior measurements.
Journal ArticleDOI
Improving generalization of MLPs with multi-objective optimization
Roselito de Albuquerque Teixeira,Antônio de Pádua Braga,Ricardo H. C. Takahashi,Rodney R. Saldanha +3 more
TL;DR: A new learning scheme for improving generalization of multilayer perceptrons using a multi-objective optimization approach to balance between the error of the training data and the norm of network weight vectors to avoid overfitting.
Journal ArticleDOI
A Multi-Objective Evolutionary Algorithm Based on Decomposition for Optimal Design of Yagi-Uda Antennas
Rodrigo Dias de Oliveira Carvalho,Rodney R. Saldanha,Bruno N. Gomes,Adriano C. Lisboa,Alexandre Xavier Martins +4 more
TL;DR: A multi-objective evolutionary algorithm based on decomposition (MOEA/D) to design broadband optimal Yagi-Uda antennas, whose optimal Pareto fronts are provided in a single picture.
