Mathematicians proved a 22-year-old graph conjecture.

The proof gives new tools for modeling routing, supply chains and epidemic spread.

A “sandwich” traps a hard graph between two well-understood bounding structures mathematicians can study directly.

Whether the proof yields a usable algorithm remains an open question.
