Introduction

In this homework, we solve MDPs with finte state and action space via value iteration, policy iteration, and tabular Q-learning.

What's Markov decision process (MDP)?

Markov Decision Process is a discrete time stochastic control process. At each time step, the process is in some state s, and the decision maker may choose any action a that is available in state s. The process responds at the next time step by randomly moving into a new state s', and giving the decision maker a corresponding reward R(s,a,s')

Setup

  • Python 3.5.3
  • OpenAI gym
  • numpy
  • matplotlib
  • ipython

All the codes you need to modified are in Lab2-MDPs.ipynb.

We encourage you to install Anaconda or Miniconda in your laptop to avoid tedious dependencies problem.

for lazy people:

conda env create -f environment.yml
source activate cedl
# deactivate when you want to leave the environment
source deactivate cedl

Prerequisites

If you are unfamiliar with Numpy or IPython, you should read materials from CS231n:

How to Start

Start IPython: After you clone this repository and install all the dependencies, you should start the IPython notebook server from the home directory Open the assignment: Open Lab1-MDPs (students).ipynb, and it will walk you through completing the assignment.

TODO

  • [30%] value iteration
