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…
