Chain-of-Thought Prompting Enhances Transformer Branching Complexity

A new research paper explores how Chain-of-Thought (CoT) prompting can enhance the capabilities of Transformers, particularly in handling branching complexity. The study provides concrete constructions for depth-first search and Dijkstra's algorithm using CoT, demonstrating their efficiency in computing tree properties like Strahler number and width. These constructions are notable for their depth-bounded nature and ability to handle arbitrary n-ary trees without relying on positional encodings. AI

IMPACT Demonstrates how CoT can unlock new computational capabilities in LLMs, potentially leading to more complex reasoning and problem-solving.

    Chain-of-Thought Shows the Path to a Tree: Realizing Branching Complexity

    arXiv:2608.11716v1 Announce Type: new Abstract: Chain of Thought (CoT) lifts the expressive ceiling of bounded-depth Transformers, with characterizations tying the number of CoT steps to circuit complexity classes. What remains largely missing are concrete instantiations with exp…
