Reference materials prepared by the HKOI Organizing Committee
The HKOI Organizing Committee has prepared some explanatory notes on algorithms commonly used in software competitions. Schools and students in Hong Kong are welcome to use them as reference for teaching and learning. These are taken from the draft version of the published book distributed a few years ago. Errors and omissions are expected. Comments and suggestions are welcome.
