With the introduction of Function Approximation methods in Part 4, we are ready to solve Reinforcement Learning problems in more complicated environments with dynamic and continuous states. In this article, we will further extend this knowledge to solve Multi-Agent Reinforcement Learning problems in these environments. To refresh our understanding of Function Approximation and Deep Q-Networks for single-agent settings, check out the previous article (Part 4) below:

So far, we have dealt with a single decision-making agent that aims to act optimally under uncertainty in an environment to produce maximum long-term reward relative to a task. In Multi-Agent Reinforcement Learning, however, there is an added layer of complexity in which more than one agent is present, and these agents could either be cooperative or adversarial, or a mix of both. In these settings, each agent’s state includes observation not only about itself but also about other agents’ positions and their activities.

In training adversarial multi-agent models, the goal is for all competing agents to discover the optimal strategies against opposing parties by reaching a game state called Nash Equilibrium. As such, adversarial Multi-Agent Reinforcement Learning can be adapted and… Read the full blog for free on Medium.
