Challenge: Long reasoning steps in LLMs improve reasoning abilities, but the correlation between their effectiveness and the length of reasoning steps remains largely unknown.
Approach: They conducted experiments that expand and compress the rationale reasoning steps within CoT demonstrations while keeping all other factors constant.
Outcome: The results show that lengthening the reasoning steps in prompts significantly enhances LLMs’ reasoning abilities across multiple datasets.
