Time-for-Accuracy: Formalizing Chain-of-Thought as an Expansion of Logical Depth
Yue Wang · Zhi Zhang · Wang Xi · Chengjie Sun · Lili Shan · Bingquan Liu
摘要
Chain-of-thought (CoT) often improves multi-step reasoning, but it remains unclear what kind of additional sequential computation longer traces actually enable. We connect CoT to Bennett’s logical depth, separating an answer’s description length from the sequential effort required to derive it, a...
