Exploring the challenges in multi-agent reinforcement learning

In the earlier chapters in this book, we discussed many challenges in reinforcement learning. In particular, the dynamic programming methods we initially introduced are not able to scale to problems with complex and large observation and action spaces. Deep reinforcement learning approaches, on the other hand, although capable of handling complex problems, lack theoretical guarantees and therefore required many tricks to stabilize and converge. Now that we talk about problems in which there are more than one agent learning, interacting with each other, and affecting the environment; the challenges and complexities of single-agent RL are multiplied. For this reason, many results in MARL are empirical.

In this section, we discuss what makes MARL specifically complex and challenging.

Non-stationarity

The mathematical framework behind single-agent RL is the Markov decision process (MDP), which establishes that the...

Practical Reinforcement Learning

Reinforcement learning (RL) is becoming a popular tool for constructing autonomous systems that improve themselves with experience. We will break the RL framework into its core building blocks, and provide you with details of each element. This book is divided into three parts. The first part defines Reinforcement Learning and describes the basics and the Python and Java frameworks, which we are going to use later in the book. The second part discusses learning techniques with basic algorithms such as Temporal Difference, Monte Carlo, and Policy Gradient—all with practical examples. Lastly, in the third part we apply Reinforcement Learning with the most recent and widely used algorithms, via practical applications.
