GoKawiilThree Mathematicians Prove Long-Standing 2004 Graph Sandwich Conjecture
A team of three mathematicians has finally proven the 2004 'sandwich conjecture,' which claims that any sufficiently large graph of interest can be mathematically bounded above and below by two simpler, well-understood random graphs. The proof, completed in 2025, resolves a two-decade-old open problem in graph theory by pushing existing mathematical techniques to their limits.
