About this repository

This repository is meant to be a growing collection of interesting and useful algorithms implemented in Python and presented in IPython notebooks. IPython notebooks, because they offer a convenient way for describing the algorithm, benchmarking, maybe even visualization, and eventually sharing and viewing.

I am looking forward to your contributions, suggestions, and ideas

If you have any suggestions or want to make additions, I would be very happy if you could send me

• an email,
• leave me a message on google+,
• or even send me a tweet on twitter (given you can fit it within the 140 character limit ;)).
• Or even better: It would be great if you would simply fork this project and send me a pull request.
