Welcome to The Flatland 3 Challenge!
This is the 3rd consecutive year of the Flatland Challenge! 
Participate in the challenge and push the boundaries of Multi-agent RL on trains!
What’s New in Flatland 3?
- In the previous Flatland environments, the trains departed and arrived at anytime - as the goal was to make the trains reach their destinations as fast as possible.
- However, things are quite different in the real world! Timing and punctuality are crucial to railways, and trains have specific schedules with pre-decided departure and arrival times.
- We are excited to introduce this real-life concept into the Flatland 3 environment!
Trains now have a time window within which they are expected to start and reach their destination.
