Experimenting an Artificial Bee Colony algorithm to approach the capacitated vehicle routing problem |
This paper is focused on the comparison of results obtained by the resolution of the capacitated vehicle routing problem. A modied algorithm of classical articial bee colony (ABC) is described and implemented in this article, in particular, a new type of neighborhood operator is introduced. e… | |
Weighted polynomial approximation on the square by de la Vallée Poussin means |
We consider the generalization of discrete de la Vallée Poussin means on the square, obtained via tensor product by the univariate case. Pros and cons of such a kind of filtered approximation are discussed. In particular, under simple, we get near-best discrete approximation polynomials in the… | |

Qualitative analysis and numerical approximation of an optimal control model for invasivespecies |
Invasive species cause huge amounts of environmental, economic, social and cultural damage in Europe and worldwide. Improving measures to control them is an ongoing challenge, and mathematical modeling and optimization are becoming increasingly popular as a tool to assist management (1; 2; 4). We… | |

Polluted porous media biological decontamination |
Some kind of pollutant, particularly hydrocarbon, can be removed from the polluted subsoil by means of micro organism activity. Oxygen is required during the biodegradation process and therefore air is injected in the subsoil. A multiphase and multicomponent mathematical model describing the… | |

Hypersensitive Optimal Control of Invasive Species |
Effectively dealing with invasive species is a pervasive problem in environmental management. The damages, and associated costs, that stem from invasive species are well known, as is the benefit from their removal. We investigate problems where optimal control theory has been implemented, and we… |
