The Frontier
LLM4MIP says it closed 34 open optimisation problems — MIPLIB lists 29 as incumbents
A research site says an LLM workflow closed 34 open optimisation problems. The benchmark that would have to agree lists 29 entries from the same team — and none of them as proven optimal. The gap is the story. An LLM-assisted workflow now claims 34 of 132 open MIPLIB instances "resolved" — but MIPLIB's own log carries 29 of those submissions, all as incumbent improvements, not proofs. The work is LLM4MIP, published as a research website on 21 September by Yicheng Huang and Wenzhi Gao as co-lead
