MADDPG in Ray/RLlib

Multi-Agent DDPG in Ray/RLlib

Notes

• The codes in OpenAI/MADDPG were refactored in RLlib, and test results are given in ./plots.

  • It was tested on 7 scenarios of OpenAI/Multi-Agent Particle Environment (MPE).
    • simple, simple_adversary, simple_crypto, simple_push, simple_speaker_listener, simple_spread, simple_tag
      • RLlib MADDPG shows the similar performance as OpenAI MADDPG on 7 scenarios except simple_crypto.
  • Hyperparameters were set to follow the original hyperparameter setting in OpenAI/MADDPG.

• Empirically, removing lz4 makes running much faster. I guess this is due to the small-size observation in MPE.
