AI Reportedly Solves 25-Year-Old Open Math Problem in Wireless Comms

Researchers have found that frontier AI models (like GPT-5.6 and Claude Fable) appear to have successfully solved a 25-year-old theoretical problem in wireless communications (integer least squares for MIMO detection).
The problem explores how to perfectly recover all transmitted bits in a Gaussian wireless channel when the signal-to-noise ratio meets a specific threshold. The author, who previously worked on this problem during their PhD, discovered the polynomial-time solution simply by prompting the AI, demonstrating the immense potential of LLMs in tackling complex mathematical and engineering challenges.
