A new research paper explores the limitations of teaching complex reasoning tasks to AI models through chain-of-thought (CoT) fine-tuning. The study found that while models can readily learn forward-computable tasks, they struggle with procedures involving backtracking search, such as cryptarithms. Even with extensive fine-tuning and various methods like RL, the models fail to imitate the search process effectively, instead learning to mimic specific steps without understanding the underlying logic. The research suggests that for tasks requiring search, pre-computing solutions and focusing on memorization and verification is more effective than attempting to teach the search procedure itself. AI
