One of the main difficulties for this multi-agent problem is to define a suitable observation with allows for great scalability of the algorithms as well as generalizability across many problem instances.
We have provided you with three basic observations: Global, Local Grid and Tree Observation. And we encourage you to build on these or invet novel observations that help solve this problem.
This Thread is used to discuss different aspects, benefits or drawbacks of the provided observation and help us collaboratively come up with better solutions.
Here are the base observations provided by us: Observation builders
