Abstract

We present a novel approach to chain-of-thought reasoning that achieves human-level performance on mathematical reasoning tasks. Our method combines structured prompting with self-consistency techniques, resulting in a 23% improvement over baseline models on the MATH dataset.

Method Overview

# Simplified pseudocode of the approach
def structured_cot(prompt, model):
    # Step 1: Generate multiple reasoning paths
    paths = [model.generate(prompt) for _ in range(k)]
    
    # Step 2: Verify each path
    verified = [verify(path) for path in paths]
    
    # Step 3: Self-consistency voting
    answer = majority_vote(verified)
    
    return answer

Validation Status

Reproduced by our team: 18% improvement (close to claimed 23%)
Tested on GPT-4o, Claude 3 Opus, Gemini Pro
Computational cost analysis confirmed
