Not evaluated
One-sample matroid prophet inequalities against an almighty adversary (family 111)
The gist
On October 6, 2026, OpenAI announced, from an unreleased internal model, a manuscript on matroid prophet inequalities against an almighty adversary, with Lean files.
DiscoverIA status on October 12, 2026: not evaluated, meaning no third-party evaluation found.

What it changes
If the manuscript were correct, it would show, according to its title, that one sample suffices for prophet inequalities on matroids, against an adversary described as “almighty”. A matroid is a family of sets of items that can be chosen together, subject to an exchange rule.
What remains unclear
The Lean files (Lean is a language in which a computer checks every step of a proof) are supplied by OpenAI itself, and the repository marks them “unchecked”. No third-party verification is recorded.

Method
The manuscript “One Sample Suffices for Matroid Prophet Inequalities against an Almighty Adversary” makes up family 111. It is dated September 23, 2026 and filed under the section “Theoretical computer science” of overview.tex. The file lean/docs/111.md describes the scope of the formalisation, with two Comparator statements. They are in lean/ComparatorChallenges/MatroidProphet.lean and lean/ComparatorChallenges/MatroidSecretary.lean. The family is not among the sources of formalization.yaml; history.md reports no revision. DiscoverIA status: not evaluated, meaning that no third-party evaluation has been found in the sources read. Set on October 12, 2026 from github.com (page read, quotation checked word for word: “describes the scope of the Lean formalization”).
Limits
No named third party: the recorded checks come from the claimant or from a platform tool. The claimant supplies a Lean proof; as of this date, DiscoverIA has found no independent verification of this proof or of the result.
