RLVR typically adopts group-relative policy optimization methods such as GRPO, sampling a group of rollouts for the same prompt, using an outcome verifier to give 0/1 rewards, and then updating the policy with the standardized within-group reward as the advantage function.

VerifiedGRPO samples a group of multiple outputs for the same input and uses the mean reward within the group as the baseline to compute the advantage function, thereby eliminating the value network and reducing memory and computation overhead.74% similarUnverifiedVAG uses verifier advantage (the task-level signal of RLVR) as the optimization anchor, ensuring that the overall direction of policy updates does not deviate from verifiable correctness.71% similarVerifiedThe GRPO algorithm directly compares the quality of a group of answers to the same question through an intra-group relative reward mechanism, eliminating the need for the separate critic model required by PPO.70% similarUnverifiedGRPO is naturally suited for verifiable tasks, and in scenarios such as mathematics and coding, rule-based rewards can replace complex reward models.67% similarUnverifiedThe core component of RLDS is the Subtask-Decomposed Advantage Estimation (SDAE), designed as a replacement for the scalar GRPO advantage function.67% similar
