rl algorithms

This repository contains Jupyter notebooks of different Reinforcement Learning (RL) algorithms implementations. Each notebook implements a single RL algorithm in a self-contained and complete manner.

Docker:

In order to use Docker you should first build the image by running the following Shell command in the repository directory.

docker build -t rl_alg:latest .

Then, run the following command to create a container out of that image, connect it to port 8888 (the Jupyter port), and bind the notebooks directory in the container to the notebooks directory on the host (on your machine).

docker run -d -p 8888:8888 -v ./notebooks:app/notebooks rl_alg

Finally, open a browser on your local machine and go to

localhost:8888

and enter in the Jupyter password the word admin. A Jupyter-Lab interface should open with a locally mounted notebooks directory in it.
