There was a problem hiding this comment.
NEAlgorithm is already having ABC, so no need to put ABC here?

LGTM! |

Add a simple implementation of the MAP-Elites algorithm (ref1, ref2), with an example on the Brax Ant task.
Users can implement their own behavior descriptor extractor, see an example in
task/brax_task.py.Example commands
python train_ant_map_elites.py --max-iter=3000 python train_ant_map_elites.py --max-iter=3000 --save-gif # This can be slowExample output
Note We plan to add more Quality Diversity methods, the implementations and related interfaces are subject to change.
