## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 2406, "days_push": 2406, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of competitive programming (OI) lecture slides from 2013-2018, written in TeX and published as PDFs. Topics include network flow models, graph theory, dynamic programming, data structures, number theory, linear algebra, and contest strategy.

## Use cases
- learn competitive programming algorithms
- study network flow modeling techniques
- prepare for informatics olympiad contests
- find dynamic programming practice problems
- learn graph theory for NOIP-level contests
- get contest strategy advice

## When to choose
- you are training for OI/NOIP/provincial selection contests
- you want curated problem sets with explanations on classic algorithm topics
- you read Chinese and want lecture-style material

## When to avoid
- you need English-language material
- you want interactive exercises or an online judge
- you need up-to-date content - slides were last revised in 2018

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: education, tutorials
- platform: cross-platform
- tags: competitive-programming, olympiad-informatics, latex-slides, lecture-notes, chinese, algorithms
