The weighted independent domination problem: ILP model and algorithmic approaches

Davidson, P.P.; Blum, C.; Lozano, J.A.

(2017-06-01)

This work deals with the so-called weighted independent domination problem, which is an N P -hard combinatorial optimization problem in graphs. In contrast to previous theoretical work from the liter- ature, this paper ...

An investigation of clustering strategies in many-objective optimization: the I-Multi algorithm as a case study

Castro, O.R.; Pozo, A.; Lozano, J.A.

; Santana, R. (2017-03-30)

A variety of general strategies have been applied to enhance the performance of multi-objective optimization algorithms for many-objective optimization problems (those with more than three objectives). One of these strategies ...

Analysis of a hybrid Genetic Simulated Annealing strategy applied in multi-objective optimization of orbital maneuvers

Shirazi, A.

(2017-03-27)

Optimization of orbital maneuvers is one of the main issues in conceptual and preliminary design of spacecraft in different space missions. The main issue in optimization of high-thrust orbit transfers is that the common ...

Multi-objective Optimization of Orbit Transfer Trajectory Using Imperialist Competitive Algorithm

Shirazi, A.

(2017-03-04)

This paper proposes a systematic direct approach to carry out effective multi-objective optimization of space orbit transfer with high-level thrust acceleration. The objective is to provide a transfer trajectory with ...

Hybridizing Cartesian Genetic Programming and Harmony Search for Adaptive Feature Construction in Supervised Learning Problems

Elola, A.; Del Ser, J.

; Bilbao, M.; Perfecto, C.; Alexandre , E.; Salcedo-Sanz, S. (2017-02-28)

The advent of the so-called Big Data paradigm has motivated a flurry of research aimed at enhancing machine learning models by following very di- verse approaches. In this context this work focuses on the automatic con- ...

An efficient approximation to the K-means clustering for Massive Data

Capo, M.; Pérez, A.

; Lozano, J.A.

(2017-02-01)

Due to the progressive growth of the amount of data available in a wide variety of scientific fields, it has become more difficult to manipulate and analyze such information. In spite of its dependency on the initial ...
