Optimization Days is an annual conference organized alternately by the Interuniversity Research Centre on Enterprise Networks, Logistics and Transportation (CIRRELT) and the Groupe d'Études et de Recherche en Analyse des Décisions (GERAD). The meeting aims to survey current research trends in optimization methods and their applications and provide an opportunity for interaction between various research groups worldwide. Topics of interest include, but are not restricted to:

• Mathematical programming, heuristics, constraint programming, optimal control theory, numerical methods of optimization, statistical methods, and applications to engineering, management science, healthcare systems, transportation, economics, urban and environmental problems, resource management, biology, telecommunications networks, robotics, expert systems, energy modeling, etc.

All those interested in optimization methods and their potential applications are invited to participate. We are also interested in talks on methods lying at the intersection between optimization and machine learning. The languages of the conference will be English and French.

The conference will be held at HEC Montréal, 3000 Côte-Sainte-Catherine, Montreal, near the Campus of the Université de Montréal.

In 2025, Optimization Days will host the International Conference on Variable Neighborhood Search (ICVNS). Participants of both Optimization Days and ICVNS 2025 can attend talks from either event and interact during shared coffee breaks and the social event.
