18 February 2018: Changing Statistical Data View
It is now possible to change the statistical data shown on the Statistics pages from the default view of all registered members to active members only; that is, members who have solved a problem within the last 365 days.
10 February 2018: New BBCode [Collapse]
A recent BBCode has been added to the forum: [collapse], allowing members to post blocks of text that can be expanded and collapsed. It works in the same way as the code block, except you can use any other formatted text within it, including TeX. For more information on the usage of this tag and the others, then please see:
It may be useful when you wish to post a lengthy section of text (for example, proofs or program output) which might otherwise interfere with the brevity of your post. Similarly if you wish to hide solutions/spoilers relating to extension questions posed by members on the current problem.
On the subject of spoilers, it has been noted on occasion that some members have posted comments like, "I used the same code to solve problem XXX" or "By changing your algorithm in the following way you can solve problem YYY". We understand that this has always been well meaning, but other members may not have solved that problem yet and would like to tackle it independently for themselves. So we would ask that members, when referring to other problems, hide the reference with the hide tag or the new collapse tag for longer replies; see link above for usage.
2 September 2017: Start of the new season
The new season will start Saturday, September 9th, 2017, 16:00 server time.
Last year it became challenging for the team to continue with the weekly publication scheme. Now that we have over 600 problems published, finding new and interesting problems is becoming increasingly difficult.
As long as we have a sufficient number of problems that are ready for publication then we are able to maintain a weekly release of new problems. However, we currently do not, so we have made a decision to reduce the release of new problems to one problem every two weeks. If we can re-establish enough ready-to-publish problems, then we will return to weekly publication.
As you are aware, many of the excellent problems that we have learned to enjoy have come about through the contributions of our members. If you have any interesting ideas for new problems, then please consider making a problem proposal. See Suggesting New Problems for more information on the process.
10 August 2017: Summer 2017 Website Update
A major rewrite of the main website back end has been taking place on my local machine for some time and on 10 August 2017 the updated scripts were uploaded. It is hoped that the changes made will provide a little more fluidity and robustness to the functionality of the website. Sadly, very little has been done in terms of cosmetics, so you are unlikely to notice much on the surface, but I can assure you that significant changes have been made to the way the website handles data.
With any update there is only so much testing that can be done locally before the changes are made to the production website. So it would be very helpful if the thread: Summer 2017 Website Update at the Project Euler forum is used to report any bugs that you might identify. I would ask for your patience if any bugs or issues come to light as I hope the necessary changes will benefit all of us in the long term.
14 June 2017: Summer break
Problem #608 (Saturday, 17th June 2017, 04:00 pm servertime) will be the last problem before the summer break.
We will be back Saturday, September 9th, 2017.
