IG-Search computes step-level information gain rewards from policy probabilities to improve credit assignment in RL training for search-augmented QA, yielding 1.6-point gains over trajectory-level baselines on multi-hop tasks.
Search-E1 uses GRPO interleaved with on-policy self-distillation to reach 0.440 average EM on seven QA benchmarks with Qwen2.5-3B, outperforming open-source baselines.
SD-Search derives step-level supervision for search queries in reasoning agents via on-policy hindsight self-distillation using the policy as both student and teacher.
