Statistics Update (19 May 2026)
Posted: Tue May 19, 2026 7:00 pm
We are very grateful for the understanding shown after sharing the difficult decision to remove the fastest solvers tables in their current form, and as promised, we will be working in the near future to consider a replacement.
The reason for the removal of the fastest solvers tables means that the Eulerians table, which shows the "successes" of recent solvers, has become equally polluted with cheats. As a result, they will be removed in the next day or so. The good news is that at the same time we will be introducing a new data packed table in the Statistics section that shows the ranks of the problem set over the past 28 days, as well as the lowest/highest ranks seen (with dates). The data has only been captured across all problems since 17 April, which marks the time when we made the final tweaks to the rating algorithm, but it already provides useful insights. In addition, below each problem you will be able to see a graph showing the movement of ranks over the past 28 days. The minimal API will also be updated to allow members to capture current snapshots of problem difficulty ranks (using minimal=problems).
Once again, thank you for your understanding, and we hope that this does not detract from the main reason we have such dedicated and engaged members: the problems. We hope that you will enjoy the upcoming problems, especially as we celebrate the publication of the landmark problem 1000 shortly.
