The research project Modelling and Optimization of Large-Scale Structured Problems and Applications (MOLSA) has been accepted for granting by the Spanish's National Program of R+D+i for the Challenges of the Society. The project's leaders are prof. Jordi Castro and F.-Javier Heredia, from GNOM, with a research team involbiong professors of the UPC and the Euskal Herriko Unibersitatea (Basc Country, Spain). The ultimate goal of this project is to develop optimization methods for large problems (which usually implies a certain structure in the problem), both deterministic and stochastic, and their application to real cases. The project herefore pursues both methodological and applied objectives.
