    "body_text": "AutoSR searches persistent research states rather than isolated formulas. Proposer and reviewer agents add motivations, computational evidence and criticism to each branch, while progressive-widening Monte Carlo tree search allocates work among competing investigations. Across nine selected benchmark challenges, the authors report algebraically equivalent recoveries in every case, including three cp3-bench problems not recovered by published comparison systems. The small selected suite supports the workflow concept, not a general claim of autonomous scientific discovery.",
