# Hacktoberfest 2026 preparation — open PR cleanup tracker

This file tracks the cleanup of open pull requests ahead of [Hacktoberfest 2026](https://hacktoberfest.com) so the queue is ready for the October influx of contributions.

Each of the `scripts/close_pull_requests_with_*.sh` jobs is run one at a time by a maintainer. After each run, the affected lines below are checked off (`[ ]` -> `[x]`), their labels replaced with "closed by <script name>", and the totals table at the bottom updated.

Snapshot taken: **2026-09-02** -- **918** open pull requests.

Latest refresh: **2026-09-06** -- reconciled the tracker with the live PR queue: **84** more tracked PRs are now resolved (**10 merged**: #13862, #13903, #14038, #14260, #14291, #14307, #14346, #14562, #14663, #15182; **74 closed**). Approximately **669** pull requests remain open.

Notation: `<index>. [ ] #<pr_id> <labels>`

## Open pull requests grouped by algorithm directory

_Generated by examining the changed files of every open PR. Each PR appears in exactly one grouping. PRs touching more than one algorithm directory are under "Modifies multiple algorithm directories"; PRs touching only non-algorithm paths (e.g. `.github/`, `scripts/`, `docs/`) are under "Modifies no algorithm directories"; PRs that touch `DIRECTORY.md` without touching an algorithm directory are under "Modifies DIRECTORY.md"._

## Creates a new root directory

_As requested by @cclauss on #15184: open PRs that add a **new top-level directory** to the repository (a directory that does not exist on `master`). These need a maintainer decision on whether the new category belongs in the collection before the code review matters, so they are grouped separately from the by-directory listing above. Each PR was confirmed to add at least one file under a top-level path that is absent from `master`._

Total PRs that create a new root directory: 13

### Triage recommendations

A first pass at *which open issues we can close*, ordered by confidence. Grouped so a maintainer can act on a whole bucket at once. I verified each claim against the current `master` tree before listing it; where a claim depends on something I can't see (e.g. a rebuilt container), it's marked **verify**.

**A. Close now — not a real issue / spam**

- **#15002 "Sin gravedad"** — spam. Body is an advertising link to an adult cam site, reports "Python 5.0", and attaches a video. No algorithmic content. Close and, if possible, report the author.

**B. Close now — obsolete (target no longer in the tree)**

- **#13226 "Inconsistent behavior for missing values in `coordinate_compression.py`"** — the file `data_structures/coordinate_compression.py` no longer exists on `master`; the module the bug is about has been removed. Nothing left to fix.

**C. Close as fixed/duplicate once the linked PR merges**

- **#15085 "[BUG] `jump_search` raises `IndexError` for empty list input"** — still reproduces on `master`, but a fix is already in the review queue: **#14807** (canonical `jump_search([]) -> -1` guard + doctest, which I've approved) with **#15101** as a duplicate of it. Close #15085 as fixed the moment #14807 merges; no separate fix PR is needed.

**D. Stale feature requests with no implementation ("please add algorithm X", ≥1 year, no PR)**

These are standing "it would be nice to have …" requests that never produced a PR. They're not bugs and nothing in the tree depends on them; leaving them open makes the issue list look busier than the actual work. Recommend closing with a friendly "we'd still welcome a PR for this — closing to keep the tracker actionable; comment and we'll reopen" note. Candidates (all `enhancement`, 600–1500 days old, zero linked PR):

- #8067 XGBoost classification/regression · #8083 caching algorithms · #11517 sliding window · #11578 genetic algorithm for function optimization · #11837 LZ78 compression · #11844 transposition cipher · #11938 travelling salesman · #11947 wildcard matching with FFT · #11972 Grover's search (Qiskit) · #12043 Edmonds' Blossom · #12064 elliptic-curve crypto · #12069 LSTM · #12107 hollow-diamond pattern · #12108 ridge regression · #12124 adaptive/"stalin" merge sort · #12128 TSP in graphs · #12218 set-matrix-zero · #12318 Shor's algorithm · #12321 ART1 net · #12322 RBFNN · #12496 "addition of AI algorithms" · #12569 collision detection · #12622 PID/ADRC · #12939 transitive closure

**E. Likely already resolved — verify then close**

- **#10941 "Container build failed in codespaces"** and **#11812 "DevContainer setup fails"** — a working `.devcontainer/` (Dockerfile + `devcontainer.json` + `post_install`) is present and current on `master`; both reports predate it. **Verify** a fresh Codespace build is green, then close.
- **#11841 "computer_vision README.md link not working"** and **#11225 "Misformatted/linked wiki entry in python sorting"** — small doc-link reports; **verify** the referenced link resolves today and close if fixed.

**F. Keep open — real, reproducible, and good contributor material**

Confirmed still-live on `master` and each is a tidy, well-scoped fix (good `good first issue` candidates), so these should stay open:

- #14950 `radix_sort` doesn't raise on negative input (verified: silently mis-sorts) · #14898 `cyclic_sort` infinite loop on invalid input · #14649 `split` wrong result for multi-character separators · #15071 Kahn's topo-sort `pop(0)`/sparse-id bug · #15075 `matrix_exponentiation` self-referential annotation `NameError` · #14584 `run_simplex()` returns `{}` instead of raising · #12192 topological sort returns reversed list · #12233 avoid `log(0)` in KL divergence.

I can take a second pass through the remaining `awaiting triage` items (relabel or route) once the buckets above are actioned — just say the word.
