Project Euler: Mathematics & Logic Puzzles for Computer Programs

A website dedicated to computational problems requiring math, logic, and programming skills to solve, with a series of puzzles involving mathematical concepts.

What is Project Euler?

Project Euler is an online platform that hosts a collection of over 750 mathematical problems aimed at encouraging both mathematicians and programmers to solve computational and logic-based puzzles. The problems on Project Euler range in difficulty from relatively simple to extremely challenging.

The core premise of Project Euler is to provide recreational mathematics questions that require a combination of mathematics, programming, and computational thinking to solve. Some problems may have simple mathematical formulas, while others require extensive programming to check millions of possibilities before arriving at the solution.

Each Project Euler problem provides some background and states the objective - usually finding some numerical answer. Hints are sometimes provided for more difficult problems. Problems are designed to be solvable in less than a minute of runtime when using an efficient algorithm on a modestly powered computer.

Solvers must write computer programs to find the solutions themselves - answers cannot simply be looked up. This encourages the use of programming and computational thinking skills. Languages like Python, C++, and MATLAB are commonly used, but any programming language can be applied.

In addition to the main problem set, Project Euler offers forum discussions for each question, promoting collaboration and the exchange of ideas between math and programming enthusiasts around the world.
