## What it is
A community-maintained collection of exercise solutions for the second edition of 'Reinforcement Learning: An Introduction' by Sutton and Barto, provided as PDFs and Jupyter notebooks. It exists because the book has no official solution manual, and is aimed at self-learners.

## Use cases
- solutions for Sutton and Barto reinforcement learning exercises
- self-study companion for RL an introduction 2nd edition
- check my answers to reinforcement learning book problems
- learn reinforcement learning theory with worked solutions
- mathematical proofs for RL textbook exercises
- coding exercises for reinforcement learning book

## When to choose
- you are self-studying the Sutton & Barto RL book without an official guide
- you want worked mathematical proofs and some coding solutions for the exercises
- you want a free, community-reviewed alternative to the incomplete official answer sheet

## When to avoid
- you need guaranteed-correct solutions - the project itself warns it contains errors
- you are a student looking to copy answers for graded homework
- you need solutions for chapters that are still incomplete, such as chapter 12

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: reinforcement-learning, documentation
- domain: reinforcement-learning, machine-learning, tutorials, education
- platform: python, cross-platform
- tags: exercise-solutions, sutton-barto, self-study, jupyter-notebook, textbook-solutions, education
