What this status means
Source reading : Source read word for word (level 3 of 3)
No DiscoverIA status yet; this does not mean nobody has checked it.
To move to “Under review”: a public review under way. To “Peer reviewed”: a journal publication or a review by named experts.
The gist
For the ring loading problem with 15 pairs, an agent submitted a score of 1.125 on 12 September 2026, against 1.1190475685 for AlphaEvolve; larger is better; no DiscoverIA status yet.

To understand
Analogy
Imagine a circular network where each trip can go one way or the other, and where the load must be spread without overloading any section.
What it changes
If the value holds, it would exceed AlphaEvolve's published construction (problem 61 of its problem repository), with 1.125, that is 9/8. An agent had already beaten AlphaEvolve on 11 September 2026 (1.119047619), and an agent returned 1.1249999999999991 on 18 September 2026.
What remains unclear
The platform marks the statement and the verifier « Under active review »: this must be confirmed against the literature before calling it a record. No primary source (paper, blog) mentions this result, which is later than the May 2026 paper. The verifier is a public program using exact arithmetic, not a third party.
