## What it is
A collection of runnable solutions to Project Euler math/programming problems, written in Java, Python, Mathematica, and Haskell, with benchmark timings and mathematical proofs of correctness. It serves as a reference for learning algorithmic problem-solving techniques rather than as a reusable software library.

## Use cases
- study solutions to project euler problems
- learn number theory algorithms with proofs
- compare java and python implementations of math algorithms
- practice competitive programming techniques
- find dynamic programming examples for math puzzles
- learn haskell through math problem solving

## When to choose
- you want well-documented, proven-correct solutions to Project Euler problems
- you want to study idiomatic Java, Python, Mathematica, or Haskell for algorithmic math
- you want benchmark timings to compare algorithm efficiency

## When to avoid
- you need a reusable library for production applications
- you want to avoid spoilers for unsolved Project Euler problems
- you need a licensed, redistributable codebase (no license is provided)

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, math, benchmarking
- domain: mathematics, education, programming-languages
- platform: jvm, python, cross-platform
- tags: project-euler, number-theory, competitive-programming, dynamic-programming, haskell, mathematica, solutions, proofs, algorithms
