They don't have an actual online judge system, all problems simply have an integer or floating point solution and they just check that you've found the value.
The only metric that matters is who solved the problem first after publication, e.g.: projecteuler.net/fastest=454. The "language" in which problems were solved is just whatever the user put in their profile, they can't actually confirm that.
Project Euler problems typically involve finding or proving and then using a lemma that makes computation of the solution feasible without brute force. As such, they live in the intersection of mathematics and computer science.
List of just the solution values:
Code solutions by individuals:Basically no one ever had the patience to solve them all. What we need is a collaborative solution.
Problems are under CC BY-NC-SA: projecteuler.net/copyright
Once you solve a problem, you can then access its "private" forum thread: projecteuler.net/thread=950 and people will post a bunch of code solutions in there.
How problems are chosen:
projecteuler.net says it started as a subsection in mathschallenge.net, and in 2006 moved to its own domain. WhoisXMLAPI WHOIS history says it was registered by domainmonster.com but details are anonymous. TODO: sample problem on mathschallenge.net on Wayback Machine? Likely wouldn't reveal much anyways though as there is no attribution to problem authors on that site.
www.hackerrank.com/contests/projecteuler/challenges holds challenges with an actual judge and sometimes multiple test cases so just printing the final solution number is not enough.

They do some really fun hardcore mathy stuff over there!
Ciro Santilli interned at Inria Centre at Université Côte d'Azur in the early 2010's. It was a disaster, largely his own fault, but also due to our broken educational system. But they do have awesome things as well.

This is a small fork of activatedgeek/LeNet-5 by Ciro Santilli adding better integration and automation for:
Install on Ubuntu 24.10:
sudo apt install protobuf-compiler
cd lenet
virtualenv -p python3 .venv
. .venv/bin/activate
pip install -r requirements-python-3-12.txt
Download and extract MNIST train, test accuracy, and generate the ONNX Extract MNIST images as PNG:Infer some individual images using the ONNX:Draw on a GUI and see live inference using the ONNX:TODO: the following are missing for this to work:
