PettingZoo

PettingZoo is the standard API for multi-agent reinforcement learning, maintained by the Farama Foundation. PettingZoo provides two stepping paradigms:

• AEC (Alternating Environment Cycle) — agents take turns sequentially

• Parallel — all agents act simultaneously

MOSAIC currently supports environments from the Classic category — turn-based board games using the AEC API.
