Spend Less, Reason Better: Budget-Aware Value Tree Search for LLM Agents

arXiv – CS AI|Yushu Li, Wenlong Deng, Jiajin Li, Xiaoxiao Li|
🤖AI Summary

Researchers propose Budget-Aware Value Tree (BAVT), a training-free framework that improves LLM agent efficiency by intelligently managing computational resources during multi-hop reasoning tasks. The system outperforms traditional approaches while using 4x fewer resources, demonstrating that smart budget management beats brute-force compute scaling.

Key Takeaways
  • BAVT provides a training-free method to optimize LLM agent performance while reducing computational costs.
  • The framework uses budget-conditioned node selection that transitions from exploration to exploitation as resources deplete.
  • BAVT achieves better performance than baselines while using only 25% of the computational resources.
  • The system includes theoretical convergence guarantees and addresses LLM overconfidence through residual value prediction.
  • Results demonstrate that intelligent resource management fundamentally outperforms simple compute scaling approaches.
