Some combinatorial optimization problems with neighborhoods
I. Espejo Miranda, R. Páez Jiménez, J. Puerto Albandoz, A. M. Rodríguez Chía
Combinatorial optimization has important applications in real world situations. Many such applications can be formulated as optimization problems defined on graphs, this is the case of planning shortest paths, spanning trees, and matching among others. However, many often the exact location of the nodes is unknown and the assumption of modelling the nodes by points should be revised. In this sense, we propose to consider uncertainty regions or neighborhoods where the points will lie very likely. We deal with combinatorial optimization problems on graphs where nodes are represented by neighborhoods that are not necessarily convex. We will develop non-linear mixed integer programming formulations with second order cone constraints and study the structure of this kind of problem.
Keywords: Combinatorial optimization, neighborhoods, SOC formulations

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.
