The main purpose of the event is to bring together Latin American and European researchers and to stimulate activities and discussions about methods and applications in the field of combinatorial optimization. Researchers from other regions worldwide are also welcome. Previous editions of the ALIO/EURO Workshop on Applied Combinatorial Optimization were held in: − − − − − − − Rio de Janeiro, Brazil (1989) Valparaiso, Chile (1996) Erice, Italy (1999) Pucon, Chile (2002) Paris, France (2005) Buenos Aires, Argentina (2008) Porto, Portugal (2011) The 2014 edition of the workshop is organized by Departamento de Investigación Operativa, Instituto de Computación, Facultad de Ingeniería, Universidad de la República, Uruguay, and is held at Edificio Polifuncional José Luis Massera, next to Facultad de Ingeniería.
