The article discusses the relationship between problems that are easy to verify and whether AI can easily learn to solve them, particularly in the context of P vs. NP problems. While the intuition that easy verification implies easy learning holds true in some scenarios, such as when a verifier provides dense training signals or reward shaping, it's not universally applicable. Key limitations include the sparse reward signals from binary verification, the fundamental difference between verification and solving complexity in NP-hard problems, and issues with distribution shift and generalization. A more accurate statement is that problems with polynomial-time verifiers can be approached by AI through iterative generation and verification, especially in average-case scenarios, but this does not equate to solving the P vs. NP question or guaranteeing worst-case performance.
