This is the code for "How to use Q Learning in Video Games Easily" by Siraj Raval on Youtube

##Overview

This is the associated code for this video on Youtube by Siraj Raval. This is a simple example of a type of reinforcement learning called Q learning.

● Rules: The agent (yellow box) has to reach one of the goals to end the game (green or red cell).
● Rewards: Each step gives a negative reward of -0.04. The red cell gives a negative reward of -1. The green one gives a positive reward of +1.
● States: Each cell is a state the agent can be.
● Actions: There are only 4 actions. Up, Down, Right, Left.

##Dependencies

-Python 2.7 -tkinter

If on Ubuntu you can install tkinter for python2.7 with $sudo apt-get install python-tk

##Usage

Run python Learner.py in terminal to see the the bot in action. It'll find the optimal strategy pretty fast (like in 15 seconds)

##Challenge

The challenge for this video is to

• modify the the game world so that it's bigger
• add more obstacles
• have the bot start in a different position

Bonus points if you modify the bot in some way that makes it more efficient
