Editorials

An editorial is the explanation of how the problem is solved — the approach, why it works, what the intended complexity is. Participants read it as a tab of the problem on the public site, next to the statement.

Editorials are written per language, like statements, and live in the editorial card at the bottom of the problem's Statement tab. You need permission to write problems.

Write an editorial

Open Problems, select the problem, and go to the Statement tab.
Scroll to the editorial card.
Click Edit, or Create editorial if the problem has none yet.
Write the editorial and save.

The editor is the same split view as the statement editor — form on one side, live preview on the other — with fewer fields: Language, the body, Automatic translation and Draft. The body accepts Markdown and LaTeX, so worked formulas and code render properly.

Editorials in several languages

The editorial card has its own language dropdown listing the languages the problem already has an editorial in, with Add translation at the bottom for a new one. On the public site, a participant asking for a language the editorial does not exist in gets the closest available one rather than nothing.

Auto-translate on the editorial card works exactly as it does for statements: pick a source language and one or more targets, and the job runs in the background while the tab shows Translation is running. Update all automatic translations refreshes everything marked as machine-produced; Override manual translations writes over hand-written editorials too. Progress is on the problem's Activity tab and in Background tasks.

Mark a machine-produced editorial with Automatic translation if you write one by hand and want later runs to be free to replace it — that flag is what auto-translation reads when deciding what it may overwrite.

Delete an editorial

Delete on the editorial card removes the editorial for the selected language, after a confirmation. Other languages, the statement and the problem itself are untouched.

What editorials are not

The editorial is published content, visible to anyone who can see the problem — it is not a place for notes to your colleagues, and it is not where participants report mistakes. Test data, checkers and reference solutions are never shown to participants; see What participants see while solving. Corrections people send you arrive as issues.
