What it changes
Problem #847 belongs to additive combinatorics (the study of sets of integers from the point of view of addition). The wiki sees a literature search here: the contribution would consist in finding an existing result, not in producing a new one.
What remains unclear
This line of the wiki cites no text from the literature and does not say what the solution contains; it reports no examination by third parties.

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(a), “Literature search” (secondary contribution). Humans named by the wiki: none; AI system: GPT-5.2 Pro. Date given by the wiki: January 19, 2026. Exact text: “Full solution found”; green flag (“full resolution”, according to the wiki's legend). 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): disproved, answered in the negative (informal_status=disproved); 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/847. DiscoverIA status: not evaluated (only the wiki's classification exists). Recorded on October 12, 2026.
