  # Multi-Agent Deep Deterministic Policy Gradient (MADDPG)
  
  This is the code for implementing the MADDPG algorithm presented in the paper:
  Multi-Agent Actor-Critic for Mixed Cooperative-Competitive Environments.
  It is configured to be run in conjunction with environments from the
  Multi-Agent Particle Environments (MPE).
  Note: this codebase has been restructured since the original paper, and the results may
  vary from those reported in the paper.

  # MADDPG: A Foundational Algorithm for Multi-Agent Reinforcement Learning in Mixed Cooperative-Competitive Environments
  
  **Status:** Archive (code is provided as-is, no updates expected). This repository provides the original implementation of the Multi-Agent Deep Deterministic Policy Gradient (MADDPG) algorithm, a key contribution for training multiple AI agents in complex environments where both cooperation and competition are present.
  
  MADDPG introduces a centralized training with decentralized execution paradigm, using a centralized critic to observe all agents' states and actions during training, which significantly improves stability and performance in multi-agent settings. This codebase is configured to be run with environments from the Multi-Agent Particle Environments (MPE).

  ## Why MADDPG? Key Differentiators
  
  MADDPG's core strength lies in its **centralized training with decentralized execution** paradigm. During training, a centralized critic observes the states and actions of *all* agents, providing a richer signal for learning. This allows for stable and effective learning in complex multi-agent environments, even when agents have diverse goals or interact in mixed cooperative-competitive scenarios. Once trained, each agent can execute its policy independently, based only on its local observations.
