In this chapter, we took an in-depth look at DP and the Bellman equation. The Bellman equation with DP has influenced RL significantly by introducing the concept of future rewards and optimization. We covered the contribution of Bellman in this chapter by first taking a deep look at DP and how to solve a problem dynamically. Then, we advanced to understanding the Bellman optimality equation and how it can be used to account for future rewards as well as determine expected state and action values using iterative methods. In particular, we focused on the implementation in Python of policy iteration and improvement. Then, from there, we looked at value iteration. Finally, we concluded this chapter by setting up an agent test against the FrozenLake environment using a policy generated by both policy and value iteration. For this chapter, we looked at a specific class of problems...

Overview of this book
With the increased presence of AI in the gaming industry, developers are challenged to create highly responsive and adaptive games by integrating artificial intelligence into their projects. This book is your guide to learning how various reinforcement learning techniques and algorithms play an important role in game development with Python.
Starting with the basics, this book will help you build a strong foundation in reinforcement learning for game development. Each chapter will assist you in implementing different reinforcement learning techniques, such as Markov decision processes (MDPs), Q-learning, actor-critic methods, SARSA, and deterministic policy gradient algorithms, to build logical self-learning agents. Learning these techniques will enhance your game development skills and add a variety of features to improve your game agent’s productivity. As you advance, you’ll understand how deep reinforcement learning (DRL) techniques can be used to devise strategies to help agents learn from their actions and build engaging games.
By the end of this book, you’ll be ready to apply reinforcement learning techniques to build a variety of projects and contribute to open source applications.
