I'm excited to share: we built a free AI coach for intro-level proof writing. It critiques drafts, points out gaps, and helps you or your students iterate without giving away the answer. Also for lapsed mathematicians to see if they've still got it. Link in the next tweet.

Marquette Stadium, the new 24,000-seat home of the Marquette University Golden Avalanche, opens in Milwaukee, Wisconsin.

@AlexanderRKlotz Confirmed. Although I could not identify the type of cookie.

Eating cookies on the pitch drop cam rn, come watch.

Over 15 years ago, I wrote a blog post with some formulas involving maximal self-avoiding walks (njohnston.ca/2009/05/on-max…). At the end of last month, @jpantone et al posted a paper that improves upon those results in ridiculously impressive ways (arxiv.org/abs/2407.18205).

@nickfleisher If you still have one, I'm interested!

@ashjasont @raymondh I think it's doing lexicographical comparison by calling __gt__ on the list object.

was genuinely puzzled when a coworker showed me this #python code today. They wanted to check if every value is greater than zero. >>> [1, 2, 3] > [0] True It didn't look right to me and I countered with this: >>> [1, 2, 3] > [1] True What is happening? @raymondh, help?

Thanks to @markmcan’s support with Charity Engine, it’s now known that the longest string of digits 1-6, such that only 121 of the digits fail to add a substring comprising a new permutation, is 643 digits long. For 122, 648 is shown, 649 to be ruled out. supermutations.net/ChaffinMethodR…

My submission for #ThisWeeksRiddler at @FiveThirtyEight. @jpantone and I found there are 322 ways to finish the race in the shortest possible time (12 moves). I went easy on @xaqwg and submitted only this one. It travels the shortest Euclidean distance (not that that matters).

26th International Conference on Applications of Computer Algebra is online and it is free. It will start this Friday. I suggest at the very least checking the program, and the book of abstracts: aca2021.sba-research.org Watch #math talks instead of YouTube over this weekend. 😛

@WisVoter @benwikler Is this conflating mail ballots with early in-person ballots? See note #4 here: elections.wi.gov/index.php/node…

WI voters have returned 89% of absentee ballots sent out: 1,738,638 out of 1,961,773. WOW Counties have highest return rate: Ozaukee 92% Washington 92% Waukesha 91% then LaCrosse 91% other notable counties Dane 90% Milwaukee 87% (282,440 out of 324,822) some small counties <80%

@markmcan Absolutely! We need all the help we can get. The links on the top of this page can help you get started: supermutations.net/ChaffinMethodR…

Our sysadmin just confirmed that the upgrade was successful. About 60 clients disconnected while the server was unreachable. Those clients should have no trouble reconnecting now. The search continues!

A message from Jay Pantone: On Thu 27 Feb, around 15:00 GMT, the supermutations.net server will be briefly down while Marquette's IT department installs new networking hardware. Depending on how long that downtime lasts, some clients may disconnect and need to be restarted.

FastDCM is a client for the Distributed Chaffin Method search that uses the GPU rather than the CPU for its calculations. Depending on the precise specifications of your system, it might run several times faster than one instance of the single-CPU client. github.com/superpermutato…

@gregeganSF My heart apparently stops several times a day. I've never noticed any side effects, so I'm not too worried.

Over 30 minutes, the scales in my gym displayed 10 random numbers with a 1 kg range that might or might not encompass my true mass. That’s just amusing ... but it makes me wonder how many fake health crises people with consumer-grade wearable health trackers suffer every day.

Please consider signing this petition, which asks the Computer and Information Sciences department at the University of Strathclyde to reconsider their plan to eliminate their Combinatorics group and fire its faculty members.

@aeliasen @gregeganSF That's correct! We just finished the computation for w=116 and started the one for w=117. Each new computation is started with 1 task. Whoever gets it breaks it up into subtasks, then those break up further, etc. There should be plenty of work in an hour or two.

@jpantone @gregeganSF This may be known and intentional, but the superpermutation server isn't sending out any new tasks at the moment.

@andrejbauer @gregeganSF Approved!

@gregeganSF How do I get my team "manually approved"? (I am probably not contributing much anyway, but I'll take brownie points if I can have them.)

[1/2] If you want to help settle the question of the shortest string with all 720 permutations of 1-6, it’s never been easier. Download DCM.jar from: github.com/superpermutato… and it will run straight from your desktop. The global collective has checked 8 × 10^{15} strings so far!
