Epoch-based Application of Problem-Aware Operators in a Multiobjective Memetic Algorithm for Portfolio Optimization
Feijoo Colomine Durán, Carlos Cotta, Antonio J. Fernández-Leiva
We consider the issue of intensification/diversification balance in the context of a memetic algorithm for the multiobjective optimization of investment portfolios with cardinality…
Metaheuristics for the Template Design Problem: Encoding, Symmetry and Hybridisation
David Rodríguez Rueda, Carlos Cotta, Antonio J. Fernández-Leiva
The template design problem (TDP) is a hard combinatorial problem with a high number of symmetries which makes solving it more complicated. A number of techniques have been propose…
Memetic collaborative approaches for finding balanced incomplete block designs
David Rodríguez Rueda, Carlos Cotta, Antonio J. Fernández-Leiva
The balanced incomplete block design (BIBD) problem is a difficult combinatorial problem with a large number of symmetries, which add complexity to its resolution. In this paper, w…
Deep memetic models for combinatorial optimization problems: application to the tool switching problem
Jhon Edgar Amaya, Carlos Cotta, Antonio J. Fernández-Leiva +1
Memetic algorithms are techniques that orchestrate the interplay between population-based and trajectory-based algorithmic components. In particular, some memetic models can be reg…
Determination of stellar atmospheric parameters for a sample of the post-AGB stars
R. E. Molina
We report for the first time the stellar atmospheric parameters for a a set of post-AGB stars classified by Suarez et al. (2006). The stellar spectra were taken from optical region…
Spectroscopic analysis of four post-AGB candidates
R. E. Molina, S. Giridhar, C. B. Pereira +2
We have done a detailed abundance analysis of four unexplored candidate post- Asymptotic Giant Branch(AGB) stars IRAS 13110 - 6629, IRAS 17579 - 3121, IRAS 18321 - 1401 and IRAS 18…
