Merged summary

TL;DR - A case study documenting how an AI research system was used over a long horizon to tighten the best known bounds on the Grothendieck constant $K_G$, alongside a candid account of what worked and what didn't in human-AI mathematical collaboration.

  • Reports improved bounds of $6\pi/11 \le K_G \le \pi/(2\log(1+\sqrt{2})) - 10^{-4}$, where $K_G$ quantifies the gap between combinatorial problems and their continuous (SDP) relaxations; the exact value remains unknown.
  • The AI system produced insights that domain experts judged genuinely novel, rather than merely mechanizing known arguments.
  • The paper's main contribution is methodological: a detailed discussion of the AI's strengths and weaknesses on long-horizon research tasks.
  • Emphasizes constructing "ideal conditions" — problem framing and workflow setup — as a prerequisite for AI-driven breakthrough insights.
