Reference implementation of the MADDPG (Multi-Agent Deep Deterministic Policy Gradient) algorithm from OpenAI's paper on mixed cooperative-competitive multi-agent environments. It is a Python library designed to train agents in the Multi-Agent Particle Environments (MPE) using TensorFlow.

Use cases

  • reproduce the MADDPG paper results
  • train multi-agent reinforcement learning policies
  • compare MADDPG against DDPG in cooperative-competitive settings
  • experiment with multi-agent particle environments
  • study centralized training with decentralized execution

When to choose

  • you need the original reference implementation of MADDPG for research or study
  • you want to train agents in OpenAI's Multi-Agent Particle Environments
  • you are comparing multi-agent actor-critic algorithms

When to avoid

  • you need a maintained library with modern TensorFlow or PyTorch support
  • you want production-ready multi-agent RL tooling
  • you need up-to-date dependencies or bug fixes
