[EN]Multi-start procedures were originally conceived as a way to exploit a local or neighborhood search procedure, by simply applying it from multiple random initial solutions. Modern multi-start methods usually incorporate ...

[EN]In this paper, we propose a tunable generator of instances of permutation-based Combinatorial Optimization Problems. Our approach is based on a probabilistic model for permutations, called the Generalized Mallows model. ...

[EN] The solution of many combinatorial optimization problems is carried out by metaheuristics, which generally make use of local search algorithms. These algorithms use some kind of neighborhood structure over the search ...

Ikaselkar (Baga-Biga) eta Erein argitaletxeetako Lehen Hezkuntzako matematikako testuliburuetan ageri diren grafiko estatistikoak ikertu dira. Identifikaturiko grafiko bakoitzean honakoa aztertu da: grafiko mota, zeregina, ...

The location of radiation sources in wireless networks is a key factor to characterize their contribution to electromagnetic exposure levels in order to deploy future networks that account for minimizing electromagnetic ...

In-band full duplex (IBFD) communications are a potential solution to spectrum scarcity. IBFD communications offer greater spectral efficiency than traditional half-duplex communications by transmitting and receiving on ...

The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown ...

The ferroelectric nematic phase (NF) has quickly become the most studied system in liquid crystal research. In this work, we investigate the origin of such polar structure by studying a compound for which the NF phase ...

En Alemania se aprecia una nueva tendencia hacia la limitación de los derechos de participación y consulta de los trabajadores en la empresa esgrimiendo el derecho comunitario. La cogestión alemana ha dejado de estar ...
