What was found
Part of a continuing series of AlphaEvolve results in combinatorics. The system evolves candidate programs under a human-specified evaluation function, so the search is automated but the problem framing is human.
Novelty check
Documented as a new observation in the Quanta coverage; the specific structure was not previously catalogued.
Caveats and known objections
The paper is an arXiv preprint, not yet peer reviewed, so this entry was downgraded from 'peer reviewed' once the artifact was located. The five authors are academic mathematicians unaffiliated with the announcing lab, and they turned AlphaEvolve's suggested permutations into proved theorems, which is what the 'independently checked' grade rests on.
Nobody outside the lab has checked this yet.
Reading the primary source closely enough to say whether it supports the claim counts as a check, and you are credited on the entry.
Or on GitHub: submit a check challenge the grade send a correction or send a pull request
Flag this for triage
Signals order the review queue and nothing else. They are never published, and they never move a grade: that takes a citation.
History of this entry
- RegradedDowngraded from peer reviewed to independently checked: the linked artifact is an arXiv preprint, not a reviewed paper.
- AddedEntered the registry graded Independently checked and Search scaffold.
Entries are never deleted. A grade that does not hold up is downgraded on the record, with the reason beside it.
Graded independently checked for verification and search scaffold for autonomy. What these mean.
