We are thrilled to announce that the ROADEF/EURO 2026 Challenge is officially open!
This year's edition, titled "Keep the Flow!", focuses on the optimization problem of T-Adaptive Segment Routing (T-ASR). Proposed by Orange Research, the challenge invites participants to design efficient optimization algorithms for routing in large-scale telecommunication networks, taking into account scheduled maintenance interventions and reconfiguration budgets.
Watch the official teaser for a quick overview of the problem: https://youtu.be/D1jubmosffI?si=tHLxgXFQkhauTjok
Key resources already available:
Detailed subject description: full technical specifications.
Initial dataset (Set A, for the sprint phase): to begin testing your algorithms.
Solution checker: a C++20 tool to validate your results.
Networktools Library: A fast header-only C++20 library for modeling and solving network optimization problems.
Prizes & Participation:
The competition is endowed with a total prize pool of €35,000, with categories for best teams, junior researchers (students), and scientific contributions.
Find all information regarding rules, organization, and the roadmap (Sprint, Qualification, and Final phases) at https://roadef.org/challenge/
We look forward to your innovative solutions and wish you the best of luck!
Sincerely,
The ROADEF challenge team: Zacharie Ales, Ronan Bocquillon, Eric Bourreau, Safia Kedad-Sidhoum, David Savourey.
The Orange Research challenge team: Amal Benhamiche, Yannick Carlinet, Morgan Chopin, Éric Gourdin, Nancy Perrot.
Bien cordialement
