    BootLoops packages particle-physics integral reduction, experimental-mathematics integer-relation fitting, and ball arithmetic into an LLM-operable exact-computation toolkit that turns multi-loop Feynman integrals, Bayesian evidence integrals, and floating-point error re-runs into exact results

    BootLoops gathers integral reduction, differential equations, and high-precision evaluation from particle physics, integer-relation fitting from experimental mathematics, exact enumeration, and ball arithmetic into one toolkit that any agentic large language model can operate and extend, computing multi-loop Feynman integrals by bootstrap methods rather than direct integration across function classes including polylogarithms, elliptic functions, and periods of K3 surfaces and Calabi-Yau manifolds, and also evaluating Bayesian evidence integrals as exact rational numbers, enumerating finite configuration spaces with proof of completeness, showing when a sought closed form cannot exist, and redoing floating-point calculations with guaranteed digits.

    Schwartz used BootLoops to have Claude compute 30 Feynman integrals end to end, 15 of them never computed before

    In a guest post, theoretical physicist Matthew Schwartz describes building BootLoops, an open-source harness for exact calculations in quantitative science: rather than asking Claude to work like a human scientist, he looked for "Claude-shaped" problems, and Claude reproduced in about 20 minutes results whose code took him weeks to write, completed 30 Feynman integrals end to end (15 reproductions of known results by the new method and 15 never computed before), then carried the same class of integral methods into ecology and population genetics, advancing 36 manuscripts across 18 fields with 19 coauthors in three months.
