Method & Evidence

AimHow can a verifier-enhanced self-play framework be designed to generate valid and challenging mathematical reasoning problems for AI training?
MethodThree-party self-play with an integrated verifier
ProcedureA 'setter' AI proposes problems, a 'solver' AI attempts to solve them, and an independent 'verifier' AI assesses the validity of the problems. The setter's reward is contingent on both problem validity (verified) and difficulty (assessed by the solver). Two verifier types were tested: a hard symbolic verifier and a soft LLM-based verifier.
