The 10th graduation ceremony of the ALGANT program last 2016 concluded with a one-day conference organized by the AAN. Privileged by the participation of Professor Jean-Pierre Serre, the day was a mix of scientific talks and non-academical contributions; its success was proved by the enthusiastic participation of former ALGANT students. It was also the occasion for many of the ALGANT alumni to meet for the first time and boosted the idea of the reinforcement of a well-organized community.
