How can I use checkio to learn more Algo?

Hi all,

Checkio has been a great source and helped me to learn Python from 0 to almost able to write anything.

However, since I'm not from computer science background, I somehow feel the lack of backbone knowledge to support bigger projects.

And I was told, learning Algo and Data Structure is essential and helpful to help me move forward. Thus, I'm writing to ask, is there any island on Checkio is more related to Algo & DS? My ultimate goal is to be able to create a Python package, such as backtesting like this: http://pmorissette.github.io/bt/

Thanks
