CDRL: Certification-Driven Reinforcement Learning for Neutrino Flavor Model Discovery

Many scientific discovery problems require searching combinatorial hypothesis spaces under complex domain constraints. Reinforcement learning (RL) offers a promising approach, but existing methods rely on scalar rewards that provide limited information about why candidate solutions fail, leading agents to repeatedly ex...

Towards Certificate-Driven Software Porting: A Self-Improving Agentic Harness for Scientific Program Optimization

CDES is introduced, which extends evolutionary search with enforceable restrictions derived from failed candidates, recorded as certificates of assumptions, checker evidence, and justified restrictions, to CPU-to-GPU translation of two particle-simulation functions from the Geant4 toolkit.
