My teammate and I held a competitive programming course at Reykjavík University in Iceland. Even though our students are Icelandic, we decided to have all material in English so we could share the course with you guys. So now we have published the slides, including LaTeX sources, the problem sets, and all supporting material. All of this can be found here.
Most of the material has a pretty open license, so you're free to do almost whatever you want with it. We hope you enjoy the material, and any suggestions for future iterations of the course are welcomed.
