I wrote Problem 619 ( https://projecteuler.net/problem=619 ) which was published on 2018-01-27 and solved by 474. The problem was based on 2013 Putnam Exam problem A2 ( https://kskedlaya.org/putnam-archive/2013.pdf ) which I took at the end of undergrad. I got an email six years later (in November 2024) telling me they accepted the problem: Greetings! Please excuse the email. It's quite possible that you are no longe…

Were you also one of Dr. Kedlaya’s students? Or just used that link? I was in an undergrad course of his and really enjoyed it. Such a smart guy.

Earlier quoted context omitted.

First of all, don't do this. No one cares. Secondly obviously every Euler solution is going to appear in the training data many times over. It's no surprise at all that an LLM can regurgitate data that was given to it.

I thought it was interesting, and I wouldn't be surprised if Euler solutions weren't in the training data, especially for the later problems like this one.

I appreciate you trying it! So at least I care.

I used to do these in college to procrastinate my homework. I always had the most difficulty with the problems that required data structures I wasn't exposed to previously and ended up making really complicated solutions that were inefficient as hell, but fun nonetheless.

I might give them a try with golang now that it's my preferred language. I used to do them in python as that was our intro language.

Perhaps you meant to reply to webo? I'm not sure what you think I might have been trying.

Project Euler spurred my love for math and programming when I was 15. I got through the first few with pencil and paper and then quickly realized I was going to need to learn how to program. Got started with Java (in Eclipse) and then moved on to Python. I feel like it completely changed the trajectory of my life.

I wrote Problem 371, https://projecteuler.net/problem=371 , as a high school student in 2012! I'm so happy to have spent twenty years of my life learning math and solving problems on Project Euler and elsewhere.

This is one of my favourite problems, I still remember that it has a very real edge case even though I solved it more than 10 years ago. Thank you for the problem!

Sounds like the birthday paradox problem. Is it?

This website was a part of my education as a computer scientist and seeing it here again I'm curious for the full story of how this site was made. Who made it, what do they do now, is it part of a broader project they have? There is only very basic info here: https://en.wikipedia.org/wiki/Project_Euler

Back in early 2000s, before hackerrank and similar coding sites, this is what my professors recommended for training programming skills.

Yeah my HS CS teacher recommended it but I don't think it was ever required

No one tells you that they delete inactive accounts. I used to have over 300 solved problems htere. Now it is all gone, all the effort, but the skill remained of course.

I still have the code for the first 50 problems in GitHub. The last commit was thirteen years ago. I don’t know why I checked these in rather than treating them as throwaway code like I did for so many other things, but I’m glad I did as I’m sure my PE account is gone now too.

A great one of my favorite websites of the past. Wonder how they are coping with the issue of their users using AI to solve problems.

It is a mostly single player game, if users want to cheat they are only cheating themselves really, right?
