CRIL in short
Lens Computer Science Research Lab (CRIL UMR 8188) is a joint laboratory between Université d’Artois and CNRS, that has a strong research focus on Artificial Intelligence and its applications. It groups together about 70 members, including researchers, lecturers, PhD students, postdocs and administrative or technical staff.
The CRIL is a member of the Confederation of Laboratories for Artificial Intelligence Research in Europe CAIRNE of the regional humAIn alliance. It is funded by Ministère de l’Enseignement Supérieur et de la Recherche, CNRS, Université d’Artois and Hauts de France region.
CRIL is located in two different places in Lens: at the faculty of science and at the technical institute (IUT).

Best Student Paper Award at ICLP 2025 for Automated Hybrid Grounding research
We’re excited to announce that Alexander Beiser (TU Wien), Markus Hecher (Univ. Artois, CNRS), and Stefan Woltran (TU Wien) won the Best Student Paper award at 41st International Conference on Logic Programming (ICLP 2025) in Rende, Italy. Their paper " on Automated Hybrid Grounding Using Structural and Data-Driven Heuristics" advances the long-standing “grounding bottleneck” in Answer Set Programming (ASP). The method decides—based on rule structure and data-aware estimation—when to use body-decoupled grounding and when to rely on standard bottom-up grounding.
