GPT-5.5 Solves Open Math Problem
khademinori · x · 2026-07-12
A repost highlights that, with prompt guidance, GPT-5.5 quickly solved a well-known open problem in discrete mathematics: the optimal bound for oblivious online vector balancing.
The original post emphasized a key insight: the author often found that their long-held "perspective" on such problems was entirely wrong. The solution provided by the model approached the issue through the lens of "the sum of 3 Gaussian distributions," making it much more tractable. The poster, who spent significant time on this problem during their postdoc, found this paradigm shift highly inspiring.
