- Expand published dataset from 15,458 to 17,797 problems (+3,573 net new mathematician problems, -1,234 archived duplicates and non-self-contained stubs with `published=false`, `archive_reason`, and `duplicate_of` links; 19,031 total records).
- Complete Erdős Problems collection (`EP-1` to `EP-1221`, 1,221 published problems) synced with `teorth/erdosproblems`, repairing 27 missing backgrounds and expanding 1,121 cryptic bibkeys into full bibliographic citations.
- Expand Kourovka Notebook (`KOU-1.1` to `KOU-21.150`, 1,934 published problems) across Issues 1–21 and the Archive of Solved Problems from `arXiv:1401.0300v48` (Oct 7, 2026), including 32 editor-confirmed `\zv` solutions and 36 `\ai` unconfirmed AI claims.
- Add 1,200 macro-expanded, self-contained open problems across 44 new open-problem collections (`AMR-113` to `AMR-156`) from 43 pure-LaTeX arXiv open-problem surveys/notebooks and Richard Stanley's Positivity Problems and Conjectures in Algebraic Combinatorics.
- Enforce…
Review 117 additional records against primary sources and independent finite checks. Correct 59 statuses, mathematical statements and AMR summaries; add Zenodo and literature references; archive 26 duplicate or malformed extracts while retaining IDs and provenance. Preserve explicit unrefereed and scope qualifications, all historical research reports, and parity with the website. Published-only counts are separate from full-export totals.
Classify the no-dense-prime counterexample as a qualified resolution
Align AIM-ALGEBRAIC_NUMBER_THEORY-0109 with the resolved classification in discussion #4 and the website update. Keep the Zenodo DOI, unrefereed-preprint qualification, and explicit limitation concerning the broader modular-interpretation question. Update status counts and preserve all statements and historical research reports.
Integrate discussion #4 status corrections and references
Apply 264 record-specific reviews from discussion #4 and all four follow-ups, with source references, explicit preprint qualifications, partial-progress scope, and research-programme tags. Confirm 90 Erdős resolutions and retain nine disputed entries as open. Reconcile legacy status fields with the dated literature reviews; refresh the dataset card and counts. Preserve all 15,458 statements and historical research reports.
Use problems.json as the default train split so the viewer treats each mathematical problem as one row instead of treating the combined dataset.json object as a single oversized row.
Release UnsolvedMath v1.6.0 with Oberwolfach Reports
Adds 6,673 open and partially solved problems from 1,106 Oberwolfach Reports (2004–2026), with DOI provenance and dated literature assessments. Total dataset size: 15,458 problems.
Remove generic confidence from the 2,084 v1.5 literature reviews. Map disproved to solved and uncertain to partially solved, using the existing UnsolvedMath status/classification taxonomy.
Add dated literature triage to the background field of 2,084 non-AMR/non-AIM problems. Preserve all AMR/AIM records and v1.4 research results unchanged.
Adds 3,359 AIM Workshop problems and their structured research reports, including 174 full solutions and 177 counterexamples. All new problems received one GPT-5.6 Sol xhigh solution attempt. Adds the AIM statement audit and removes duplicated per-problem Markdown reports from main.
Adds OpenGarden / Open Problem Garden (422 problems), Kirby's Problems in Low-Dimensional Topology (366 problems), and Kourovka Notebook New Problems (150 problems). Total dataset size is now 2,084 problems.
