Relajacion lagrangeana para el problema de particionamiento de áreas geográficas
Revista de Matemática: Teoría y Aplicaciones, 2012 Entre las metodologías utilizadas en el particionamiento territorial, destacan los modelos de localización-asignación (“location-allocation”) y los de particionamiento de conjuntos ("set partitioning”), que agrupan pequeñas áreas geográficas llamadas ...

Discrete Particle Swarm Optimization for the minimum labelling Steiner tree problem [PDF]
, 2008 Particle Swarm Optimization is an evolutionary method inspired by the social behaviour of individuals inside swarms in nature. Solutions of the problem are modelled as members of the swarm which fly in the solution space.

Multi-machine energy-aware scheduling
EURO Journal on Computational Optimization, 2017 The traditional set of manufacturing scheduling problems concern general and easy-to-measure economic objectives such as makespan and tardiness. The variable nature of energy costs over the course of the day remains mostly ignored by most previous ...

On Solving Travelling Salesman Problem with Vertex Requisitions
, 2017 We consider the Travelling Salesman Problem with Vertex Requisitions, where for each position of the tour at most two possible vertices are given. It is known that the problem is strongly NP-hard.

Rank-Sparsity Incoherence for Matrix Decomposition [PDF]
, 2009 Suppose we are given a matrix that is formed by adding an unknown sparse matrix to an unknown low-rank matrix. Our goal is to decompose the given matrix into its sparse and low-rank components.

Dense Packings of Congruent Circles in Rectangles with a Variable Aspect Ratio
, 2003 We use computational experiments to find the rectangles of minimum area into which a given number n of non-overlapping congruent circles can be packed. No assumption is made on the shape of the rectangles.
