TL;DR
MetaLadder addresses how humans solve hard math problems by recalling analogous cases. It introduces an analogy-based data sequence $QSQ'C'QC$ and a problem-restating step, enabling transfer of reasoning across similar tasks and self-evolution of training data. Across GSM8K, MATH, and out-of-domain benchmarks, MetaLadder substantially surpasses standard CoT and prior augmentation methods, with notable gains and improved generalization. The approach demonstrates that structured analogical reasoning and proactive problem comprehension materially enhance LLMs' mathematical problem-solving capabilities.
Abstract
Large Language Models (LLMs) have demonstrated promising capabilities in solving mathematical reasoning tasks, leveraging Chain-of-Thought (CoT) data as a vital component in guiding answer generation. Current paradigms typically generate CoT and answers directly for a given problem, diverging from human problem-solving strategies to some extent. Humans often solve problems by recalling analogous cases and leveraging their solutions to reason about the current task. Inspired by this cognitive process, we propose \textbf{MetaLadder}, a novel framework that explicitly prompts LLMs to recall and reflect on meta-problems, those structurally or semantically analogous problems, alongside their CoT solutions before addressing the target problem. Additionally, we introduce a problem-restating mechanism to enhance the model's comprehension of the target problem by regenerating the original question, which further improves reasoning accuracy. Therefore, the model can achieve reasoning transfer from analogical problems, mimicking human-like "learning from examples" and generalization abilities. Extensive experiments on mathematical benchmarks demonstrate that our MetaLadder significantly boosts LLMs' problem-solving accuracy, largely outperforming standard CoT-based methods (\textbf{10.3\%} accuracy gain) and other methods.
