UnverifiedStepBack takes a majority vote over candidate answers, where the trajectories participating in the vote are a mixture of the original draft trajectories and the repaired trajectories produced by resampling the suffix after the erroneous step.70% similarUnverifiedPartially recoverable errors (such as a tool call failure where an alternative exists) should trigger a fallback path.64% similarUnverifiedTraditional retrosynthesis planning methods typically use the verifier to evaluate the entire route only after the search ends, so erroneous decisions cannot be corrected in time during the search process.63% similarUnverifiedIn multi-step tool-calling chains, errors can propagate and amplify between reasoning nodes, making root-cause analysis difficult.62% similarUnverifiedA reranker can only reorder within the candidate set already recalled; it cannot pull back a correct answer that never entered the top K.60% similar
