Heurísticas aplicadas al 2D Bandwidth problem
A. Duarte, S. Cavero, E. García Pardo
El 2D Bandwidth problem (2DBP) es un problema de optimización combinatoria que consiste en encontrar una asignación de los vértices de un grafo de entrada en los vértices de un grafo huésped tal que se optimice una función objetivo. El objetivo del 2DBP es minimizar la distancia en el grafo huésped entre cada par de vértices adyacentes del grafo de entrada. En este trabajo, se propone un algoritmo basado en la metaheurística Iterated Greedy que combina un constructivo voraz, una búsqueda local y una estrategia para la destrucción y reconstrucción parcial de una solución. El método de mejora incorpora tres estrategias avanzadas para evaluar la función objetivo, diferenciar soluciones con misma función objetivo y reducir el espacio de búsqueda. El algoritmo propuesto ha sido comparado con los métodos previos del estado del arte, resultando ser el algoritmo más competitivo tanto en tiempo como en calidad de la función objetivo.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
