League of Robot Runners

The Competition

The League of Robot Runners is a competition series to foster and advance research areas in the area of Multi-Agent Path Finding. LoRR aims to:

• identify the core challenges for solving MAPF;
• develop suitable benchmark instances;
• evaluate algorithmic performance in the area and;
• track the state-of-the-art.

The competition provides a standardised system to develop, evaluate, and compare algorithmic techniques. Submissions, solutions and problem instances from the competition are open sourced, to lower barriers, promote dissemination and enable further advancements.

Competition Series

2023 Competition

The first round of the competition was held in 202 and received a total of 825 submissions from 25 teams worldwide! The competition identifies two main challenges:

• Turn actions: In MAPF, robots are often modelled as rotationally invariant agents with unit action costs. This model is disconnected from many applications, where turning actions can substantially increase achieved execution costs.
• Online lifelong problem: In MAPF, the problem is one-shot and solved entirely offline. Yet real applications are lifelong and online: agents receive new tasks upon arrival and they must be constantly planned and replanned, so as to maximise a throughput objective.

For more details about the setup, results, and resources of the 2023 competition, please visit the 2023 Competition Snapshot Site.

2024 Competition

In 2024, the competition will introduce new tracks with path planning and task assignments to reflect the challenges faced by real-world applications.
