Check out this competition on classic and dynamic versions of VRPTW: …neurips-vrp-2022.challenges.ortec.com! It builds on the #DIMACSChallenge and others and it has PRIZES! Follow EURO-NeurIPS-VRP-2022 for updates. Looks like a great event!

To those who competed in the #DIMACSChallenge, there's still time to submit to the special section of Transportation Science edited by Claudia Archetti Eduardo Uchoa and Thibaut Vidal. Details: dimacs.rutgers.edu/programs/chall…

Aaaand it's done! The qualification phase has ended! More than 800 submission were done resulting in almost 50 teams on the leaderboard! Congratulations to the top 10 teams qualifying for the FINALS with their impressive results! :)

While #NeurIPS22 on-site workshops are ongoing, we're preparing the virtual competition workshop next week Wednesday Dec 7 13:00 - 16:00 UTC. If you have not done so yet, register for NeurIPS and join the workshop!

We'll have a keynote by Thibaut Vidal, presentations by the finalists and of course the announcement of the results! You can find the full schedule and zoom link here: neurips.cc/virtual/2022/c…. (registration required)

The Implementation Challenge was a highlight of 2022. Thank you to all who participated!

Last year was rich in challenges, especially for the vehicle routing community! A retrospective of the problem variants and winning strategies by Tamra Carpenter at DIMACS: dimacs.rutgers.edu/news_archive/c… #ORMS #VehicleRouting #MachineLearning

The workshop on Computational Approaches to Vehicle Routing is happening May 22-24, 2023 DIMACS! It will feature great talks and a tribute to David S. Johnson, founder of the Implementation Challenges. Details: dimacs.rutgers.edu/events/details…

So much happening in computational tools for solving VRPs. Check out the latest from Eduardo Uchoa! 👇

VRPSolverEasy is the first practical tool for the exact solution of VRPs: (1) User-friendly; (2) Covers most classic variants and their combinations; (3) Small running times up to a respectable instance size (like 100 customers) Ruslan Sadykov Najib Errami Eduardo Queiroga

Just wrapped up a wonderful workshop that culminated in a fruitful group discussion on the future of routing algorithms. A big thank you to all participants and organizers, especially Tami! DIMACS VRP Challenge on #VehicleRouting

Toasting success of the Workshop on Computational Vehicle Routing with Eduardo Uchoa, Jorge E. Mendoza, Nick Kullman, and many students and recent PhDs who were able to attend the workshop. What a nice way to fully conclude the 12th Implementation Challenge! (Jeff Linderoth: #Routibeer?)

Thanks to DIMACS DIMACS VRP Challenge for posting my talk on the traveling salesman problem and the TSP work of the great David S. Johnson. youtube.com/watch?v=F8ZxMs…

And Jon Bentley's talk "Solving small TSPs, with David looking over my shoulder". Programming pearls for the TSP! youtube.com/watch?v=VyhPns… DIMACS VRP Challenge

The Workshop on Computational Approaches to Vehicle Routing and the David Johnson Tribute was a real highlight of 2023. We toasted its success in the annual DIMACS poster!

Congratulations to Nicole Clark-Johnson! She was recognized by Rutgers SAS for Outstanding Contributions to Operational Excellence. Anyone who has ever attended a DIMACS workshop knows that it is richly deserved! Thank you, Nicole! Rutgers SAS Mathematical & Physical Sciences (MPS)
