According to @AcerFur and cited by Greg Brockman (@gdb), a previously unsolved AI research problem now has a newly discovered proof in the literature, which is notably different from earlier methods (source: https://x.com/AcerFur/status/2012770890849689702). KoishiChan located the prior proof, and the result has been updated on the community wiki for transparency. While this does not represent a fully novel result, it highlights the importance of peer review and transparency in AI research. This development underscores the value of revisiting existing literature and community-driven knowledge sharing in accelerating AI theory and algorithm innovation.
