Jordan and coauthors tackle when to stop generator-verifier loops while controlling false discovery

A new arXiv paper by Mahmoud Hegazy, Michael I. Jordan and Aymeric Dieuleveut studies when to safely stop the generator-verifier loops common in agentic workflows.
- Problem: the verifier only proxies a costly ground-truth oracle, and as the generator searches adaptively against it, false acceptances accumulate — candidates pass the proxy but fail the ground-truth check
- Contribution: valid stopping rules that control the false discovery rate of accepted proposals
- The toolkit has independent interest: e-values built via index betting, and a novel conformal risk control procedure for non-monotone losses
- Validated on synthetic settings and a protein-design benchmark
For anyone building verification loops into agents, this turns "stop when it looks good enough" into a statistically guaranteed decision.
