Implementation of the G2RL [1] approach in the POGEMA environment.

Problem: MAPF
Environment: 2D grid with static obstacles and dynamic agents
Agent actions: wait, up, down, left, right
Local observations: free cells, static obstacles, dynamic agents
Global guidance: the shortest traversable path considering all static obstacles
Objective: minimize the overall number of steps and avoid conflicts

Partially based on the repo.
Installation:

pip install -r requirements.txt
pip install .

Notebook with simple examples of training and testing implementations.
