Project Euler Explained

Codes for Project Euler problems I have solved on https://www.ivl-projecteuler.com/

300+ Problems solved at the moment!

Side note: as of 13/03/2024, when I posted the solution to Problem 869 (bringing the total number of problems solved to 311), this website has become the largest source of detailed explanations for Project Euler available (in English)!

There are also old algorithms I initially used accompanying the final ones in some files, comments are included for a large majority of the codes, if not then please see my website!

Please take some time to read the code as it cannot be blindly copied!

NOTE: Most files contain a solution at the top, so please view them with care if you are not looking for the solution!

Essential Functions

I created my own Python Library called mathslib which contains almost all of the function I use for Project Euler (and more!)

I have also put in place some proper documentation which you can see below!

You may read the full documentation here: https://mathslib.readthedocs.io/en/latest/readme.html

View it on Github here: https://github.com/igorvanloo/mathslib

Or download it from PyPi here: https://pypi.org/project/mathslib/

Problems Finished

I will update this now and then, for fully updated version see the website
