What it changes
The wiki marks the proof by Chen and Ding (2022) as a full resolution of problem #237, which belongs to number theory. It touches on prime numbers (a prime number is an integer greater than one that is not the product of two positive integers smaller than itself). Aristotle reportedly wrote its computer-checkable version, which, if it held, would allow the proof to be checked by machine.
What remains unclear
The wiki does not name the formal language of this formalisation. The erdosproblems.com site lists a formal status of “Lean” (a language in which a computer checks every step of a proof) for the problem, without saying whether it is this formalisation. The sources read do not say who checked the formalisation or whether its statement matches the problem's.

this status is an unofficial crowdsourced classification of the problem
Method
Source: the “AI contributions to Erdős problems” wiki of the teorth/erdosproblems repository (a repository presented by Terence Tao in his blog post of August 31, 2025); frozen on June 30, 2026 (commit c8ad430, “freeze”) and read on October 12, 2026 in the git repository. Category 2(b), “Formalization” (secondary contribution). Humans named by the wiki: none; AI system: Aristotle. Date given by the wiki: April 4, 2026. Exact text: “Formalization”. Proof to formalise: Chen and Ding (2022); wiki flag on this proof: green (“full resolution”, according to the wiki's legend); the wiki does not name the formal language on this line. Literature cited by the wiki: none. Status of the problem in the teorth/erdosproblems community database (data/problems.yaml, unofficial classification, snapshot of October 12, 2026 with no commit identified, current state, not that of June 2026): proved, answered in the affirmative (informal_status=proved); a solution has been formalised in Lean (formal_status=Lean). This status concerns the problem, not this contribution. Problem page not read by DiscoverIA: https://www.erdosproblems.com/237. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
Limits
Nature: formalisation (an already known result translated into a language a machine can check), not a discovery. DiscoverIA has not checked this contribution itself.
