Re: ChatGPT

I get the impression that after the initial hype and surprise at how good it seems, enthusiasm is fading and criticism emerging. Play with the tool a bit more, and you start to think of it in terms like "it's off hallucinating again", or "it's really good at bulls***ting", or &qu...

ChatGPT

Anyone else tried testing the newfangled https://chat.openai.com/chat on Project Euler problems? (Requires an easily created openai account to use.) I did just try idly pasting the text of the first five problems into it. Bit of a mixed bag output: in all cases it gave the correct answer, but its lo...

Re: About Statistics-->Countries

Aha, I'd been wondering about this since a browser tab I had open on the old https://projecteuler.net/country=Scotland page broke and I found it again at https://projecteuler.net/location=Scotland . This thread solves the mystery... I'd suspected it was probably something related to territorial clai...

Re: Project Euler - Learning to code efficiently

I would not say that Project Euler (PE) will teach you to code efficiently; more that you will need to learn to code efficiently to solve Project Euler problems. PE itself doesn't actually give you much to show you what efficient coding looks like (apart from some hints about prime sieving in PDFs a...

Re: I just started project euler like 2 days ago.

Nice. Bit loud for me; does make me wonder about other PE logo-ed things though: a PE lapel pin maybe? Or a PE mug (with an Euler picture or some other suitably Euler-ish decor on the other side)? OEIS (if you haven't come across it yet in your Project Euler journey... you will!) were having a bit o...

Re: Favorite Problem?

Thanks for explaining your philosophy MuthuVeerappanR. Elsewhere (maybe a thread on this board) I've commented that (IMHO) Project Euler has similarities with sports like rock climbing or mountaineering where most of the competition is "with yourself" and you define your own criteria for a...

Hmmm...MuthuVeerappanR you claim to have solved problems using 12 hours and 2.5 days of computing time? Might I suggest that you might be missing the point of Project Euler? Personally I'd be unhappy submitting a solution to the site unless I had computed it in the requisite minute (those who can, s...

Re: Physics site like Project Euler?

That would be pretty cool. I do find I have more affinity for the PE problems which are a bit more on the applied side (geometrical or probability ones mainly). Recently I needed to revise my knowledge of FFTs and my first instinct was to look for a PE problem involving them... but apparently there ...

Indeed.

Any PE problems requiring Fourier Transform/FFT to solve ?

I'm curious whether there are any Project Euler problems which require a Fourier Transform to solve, either because the solution implementation actually includes FFT code, or because some analytic treatment involving FT reveals something needed for a solution. No need to give a problem number if it ...

Hmmm thanks that's very interesting information. I do probably tend to overruse BigInt; if there is any doubt about whether a problem will fit into 64bit "Long" range, I'll generally start off using a BigInt through until it becomes clear that I need some more performance to get a sub-minu...
