Hello ML and RL community
We are inviting participants to the League of Robot Runners (LoRR) 2026: https://www.leagueofrobotrunners.org
Co-located with AAMAS 2026, LoRR is a research competition on large-scale multi-robot coordination. These are important problems in a number of areas including logistics, manufacturing and computer games!
In this competition, hundreds or even thousands of robots work together to complete tasks and move efficiently across diverse maps, continuously, in real-time and at scale.
We believe ML and RL methods could be especially useful for these kinds of problems:
- The best known algorithms for computing next moves are policy-based
- Agents operate under uncertainty (move actions have a probability of being delayed)
- The challenge involves nested combinatorial problem solving (task assignment + path planning) -- a very difficult proposition for symbolic/GOFAI techniques!
This is an exciting opportunity to put your ML/RL ideas to the test on a large-scale multi-robot challenge
You can participate for fame, glory and cash prizes across three distinct tracks:
- Task Scheduling Track
- Execution Track
- Combined Track
We provide a start kit (C++/Python), example instances, validators, and a visualiser. Submissions are evaluated automatically with live leaderboard feedback.
Timeline:
- 16th April 2026: Main Round Begin
- 22nd May 2026: AAMAS prize deadline
- AAMAS 2026: AAMAS Prize Announcement
- 22nd July 2026: Main Round End
- Early August: Winner Announcement
All approaches are welcome: search/planning, RL/ML, OR, mathematical programming, robust optimization, and hybrids techniques. Visit our website for more details (www.leagueofrobotrunners.org) or post here if you have questions!
