PAPO adds a correctness-gated reward: a reward is granted only when the check succeeds and the process is concise, and effective revisions are also positively incentivized, thereby preventing the model from getting lucky by piling up large numbers of tool calls.

VerifiedResearch by Ng et al. in 1999 proved that only potential-based reward shaping guarantees that the optimal policy remains unchanged.68% similarUnverifiedReward shaping needs to be designed carefully to prevent the agent from exploiting reward loopholes and producing unintended behavior.67% similarUnverifiedThe study recommends that rather than pursuing a single perfect reward, one should systematically anticipate and test shortcuts the model might exploit, and incorporate adversarial validation into the design phase.66% similarUnverifiedIf the reward model is misaligned with the true experimental objective, the harder the search works, the further it deviates; when using reward-guided search, one should first verify the degree of alignment between the reward model and the true objective.66% similarUnverifiedThe general approach to guarding against reward hacking is to place validation logic in a sandbox outside the agent's reach and to introduce rationality checks on the solution path during reward computation.65% similar
