## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2906, "days_push": 1041, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A community collection of algorithm implementations written in the C programming language, part of the AllAlgorithms project. It serves as a reference and learning resource covering sorting, math, data structures, and other classic algorithms.

## Use cases
- learn algorithms implemented in c
- find reference c code for sorting algorithms
- study classic algorithm implementations
- contribute algorithm implementations to an open source collection
- compare algorithm implementations across languages

## When to avoid
- you need production-ready, maintained, or optimized algorithm libraries
- you need actively reviewed code or timely bug fixes, since the repository was archived in 2025 and is read-only

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: developer-tools
- domain: education, programming-languages
- platform: cross-platform, c
- tags: algorithms, c, educational, hacktoberfest, archived
