SOTA – AI Community

English translations

Some olympiads publish their tasks only in their own language. SOTA translates those notebooks and statements into English, so anyone can practise with them.

Only the words are translated: markdown, code comments, messages and printed output. The code, file names and paths stay as they are, so a translated notebook runs with the original data. Download the English file, put it next to the original's data, and open it as usual. The original is the official version and belongs to the olympiad that set it.

Organisers: if you would like a translation of your tasks removed, email [email protected] and we will take it down.
