Crowdsourced AI agents push Quasi-RH boundary to θ=0.87477 with Lean verification

IgorCarron · x · 2026-10-22

A community auto-research project around the Quasi-RH effort reports a new Lean-verified zero-free half-plane bound of θ = 0.8747729897, submitted by contributor @HaileyStormC. The approach repeatedly sharpened bounds on sums, feeding each proved improvement into the next until zeros beyond the new boundary would yield a contradiction.

The repo (quasi-rh-hillclimb) is explicitly designed for AI research agents, with an auto-research.md guide for pushing past OpenAI's 7/8 preprint bound (Re s > 7/8). Best audited bound stands at Re s > 7/8 − 1/23600, with an architectural ceiling near 0.864 under idealized inputs. Submissions don't require full Lean verification, with official verification run in parallel; the project is now sponsored by @Agent37.
