Report an error

Send the paper (arXiv id or URL), the attempt id if you have it (it is on the paper page), what you think is wrong and how you know: a value, a quote, a command or a line of the log. Anyone can report an error, not only an author. Confirmed errors are corrected and listed on What we got wrong.

Authors: right of reply

Before publishing a finding with an outcome other than “reproduced”, we notify the authors and allow at least 14 full days for a reply. Setup-only attempts abandoned before recording any result are listed as history and do not require a notice. A “reproduced” outcome gets a courtesy note at publication. Authors can reply at any time, before or after publication. Replies are published with the author's permission, in full or in the parts they choose, and any omission is marked. How release works.

Anything else

Suggestions of papers to re-run, questions about the method, the data or the MCP server, and press questions go to the same address. See also About and Privacy.
