Full story

The Grothendieck constant is a critical value in mathematics that measures the gap between combinatorial problems and their continuous relaxations. While its exact value remains unknown, recent research has successfully tightened the existing bounds using specialized AI agents.

This breakthrough was achieved through a long-horizon research system designed for human-AI collaboration. Unlike standard LLMs, this system was capable of sustained reasoning required for advanced mathematical proofs.

The new bounds established by the researchers are 6π/11 and π/(2log(1+sqrt(2))) - 10^-4. This development highlights the growing capability of AI to move beyond simple pattern matching into the realm of rigorous mathematical discovery.
