Seminario 17/11: El-Ghazali Talbi (U. Lille) – Combining metaheuristics with mathematical programming and machine learning

Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…

RWE rechnet 2013 mit deutlich hoeheren Strompreisen

Seminario 17/04: – José M. Giménez-Gómez (U. Rovira i Virgili) – The CO2 conflicting-claims problem

Abstract An effective climate agreement is urgently required, yet conflict between parties prevails over cooperation. Thanks to advances in science it is now possible to quantify the global carbon budget, the amount of available cumulative CO2 emissions before crossing the 2oC threshold (Meinshausen et al., 2009). Countries carbon claims, however, exceed this. Historically such situations have been tackled…

Seminario 17/10: – Ricardo Salvatore (U. Torcuato di Tella) – Estatura, desigualdad y cambio de régimen: La desigualdad nutricional en el largo plazo, Argentina 1875-1951

Resumen El trabajo examina la evolución de la “desigualdad nutricional” a largo plazo en Argentina. Definimos la “desigualdad nutricional” como las diferencias inter-personales al acceso a la nutrición y la salud en primera infancia. Este ensayo presenta los resultados de varias muestras de población (reclutas y presos) de diversas regiones de la Argentina. La pregunta…

Seminario 17/09: Montserrat Viladrich (U. Lleida) – Protecting biodiversity on farm land: Which type of agri-environmental measure does it better?

Abstract Much biodiversity is found in farm land. However, there is usually a trade-off between farm land productivity and sustainability of natural resources.  Biodiversity conservation in agricultural land usually requires to carry on a series of conservationist practices that are costly. Therefore, farmer’s participation in conservationist programs requires economic incentives.  Our goal is to identify…

bounds

Seminario 17/08: Michel Théra (U. Limoges) – Perturbation of error bounds

Abstract In the current presentation, I intend to extend the developments in Kruger, Ngai  & Théra, SIAM J. Optim. 20(6), 3280-3296 (2010) and, more precisely, to characterize, in the Banach space setting, the stability of the local and global error bound property of inequalities determined by proper lower semicontinuous under data perturbations. I will propose…

uncertainty

Seminario 17/07: Mª José Gutierrez (U. País Vasco) – Harvesting Control Rules that deal with Scientific Uncertainty

Abstract: By using robustness methods we design HCRs that explicitly include scientific uncertainty. Under scientific uncertainty –when the perceived model can be generated by a nearby operating model– robust HCRs are designed assuming that the (inferred) operating model is more persistent than the perceived model. As a result, a robust HCR has a steeper ratio…
