Researchers have introduced CERO, a novel online primal dual scheduler designed to optimize the allocation of rollout budgets for reinforcement learning (RL) post-training. Unlike traditional methods that fix per-update budgets, CERO coordinates a finite budget across the entire training horizon by adapting prompt selection, revisit frequency, and group generation. This approach utilizes a compact Fenchel representation and projected online gradient descent, achieving superior performance on mathematical reasoning benchmarks compared to fixed-rate and time-varying benchmarks.
