A personal mirror of the MAMUT-routing benchmark catalog

I have put up a personal mirror of the MAMUT-routing benchmark catalog, now live at mamut-routing.onyr.net. It serves a complete, static copy of the catalog from my own server, so the instances and their documentation stay reachable independently of the official site.

What MAMUT-routing is

MAMUT-routing is the public benchmark and instance catalog of the ANR-MAMUT project (Machine learning And Matheuristics algorithms for Urban Transportation, grant ANR-22-CE22-0016), run at Université Bretagne Sud (Lab-STICC). It catalogs vehicle-routing instances, from the classic VRPTW and CVRP families to modern time-dependent TDVRPTW and TDVRP families, each shipped in a documented JSON format with per-instance best-known solutions and a clearly stated objective contract. The benchmark catalog is developed by Adrien Pichon and mylself under the supervision of Romain Billot, Lina Fahed, Alexandru-Liviu Olteanu, Marc Sevaux and Christine Solnon within the ANR-MAMUT project, and I am glad to help make their work more visible in this AI-driven fast-paced field of vehicle routing optimization.

What the mirror serves

The mirror is a faithful, static copy of the upstream site:

As a small taste of the catalog, here is the Poryos2026 time-dependent family, a set of instances whose congestion comes from real city road networks. I write more about it in a companion post on the Kayros solver.

Why a personal mirror

This is my own independent mirror, not a fork, though it might evolve in the future to include additional features or elements that matter to my PhD research. As of now, very page carries a disclosure banner making that clear and linking back to the source. The official site, mamut-routing.univ-ubs.fr, is temporarily unavailable, so this mirror is a convenient stand-in in the meantime. When the official site is back, it remains the canonical reference.
