Prologin is a non-profit organization, which organizes a yearly Computer Science contest of the same name. It is run by 60+ volunteers. Since 1992, the Prologin contest brings together computer science enthusiasts. The contest is divided in three parts: an online selection phase open to everyone, semi-finals taking part in a few French cities, and for the best 100 candidates, the final in Paris: 36 hours of non-stop programming and fun!
