LOCATION OF THE WORKSHOP

The workshop takes place at the Université de Lille 1, Amphi Turing, Bâtiment M3 (first floor), Cité Scientifique, Villeneuve d'Ascq, in the north of France. This lecture hall is located just beside the Laboratoire d'Analyse Numérique et Optimisation (follow this link for a more precise description how to join the Laboratoire ANO).
