A Novel Reliability-based Robust Design Multi-objective Optimization Formulation Applied in Chemical Engineering
Gustavo Barbosa Libotte, Fran Sérgio Lobato, Francisco Duarte Moura Neto +1
Mathematical models simulate various events under different conditions, enabling an early overview of the system to be implemented in practice, reducing the waste of resources and…
Basins of attraction and critical curves for Newton-type methods in a phase equilibrium problem
Gustavo Mendes Platt, Fran Sérgio Lobato, Gustavo Barbosa Libotte +1
Many engineering problems are described by systems of nonlinear equations, which may exhibit multiple solutions, in a challenging situation for root-finding algorithms. The existen…
Geometrical Tools for Teaching Azeotropy Using Simplified Thermodynamic Models
Gustavo Mendes Platt, Gustavo Barbosa Libotte, Francisco Duarte Moura Neto +2
In this work we propose a geometric view of the azeotropy problem, using some simplified models. We demonstrate that the occurrence of azeotropes in binary mixtures can be viewed-g…
MDE-ITMF and DEwI: Two New Multiple Solution Algorithms for Multimodal Optimization
Vinícius Magno de Oliveira Coelho, Gustavo Barbosa Libotte, Francisco Duarte Moura Neto +2
Mathematical formulations of real world optimization studies frequently present characteristics such as non-linearity, discontinuity and high complexity. This class of problems may…
