Summary
This research paper analyzes the reasoning capabilities of Large Language Models (LLMs), arguing that current reasoning LLMs lack systematic problem-solving abilities and instead behave as 'wanderers' rather than systematic explorers. The study identifies common failure modes including invalid reasoning steps, redundant explorations, and hallucinated conclusions, and finds that model performance degrades significantly as task complexity increases. The authors advocate for new evaluation metrics that assess the reasoning process structure rather than just final outputs.
Key quotes
· 5 pulledLarge Language Models (LLMs) have demonstrated impressive reasoning abilities through test-time computation (TTC) techniques such as chain-of-thought prompting and tree-based reasoning.
However, we argue that current reasoning LLMs (RLLMs) lack the ability to systematically explore the solution space.
This paper formalizes what constitutes systematic problem solving and identifies common failure modes that reveal reasoning LLMs to be wanderers rather than systematic explorers.
Our findings suggest that current models' performance can appear to be competent on simple tasks yet degrade sharply as complexity increases.
Based on the findings, we advocate for new metrics and tools that evaluate not just final outputs but the structure of the reasoning process itself.
