+## 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"._
