Four-Color Theorem Gets a Rare New Proof, Revisiting Its Controversial 1970s Computer-Assisted Solution

Quanta Magazine reports that mathematicians have produced a rare new proof of the four-color theorem — the statement that four colors suffice to color any contiguous map so no neighboring regions share a color. The theorem was first proven in the 1970s with computer-assisted exhaustive checking, a controversial approach that many felt offered little theoretical insight.
The new proof stems from deeper insights into the nature of graphs, answering a long-standing desire for a more human-comprehensible argument. Some are now calling on frontier AI labs to attempt finding a short proof — which would be a landmark moment for math and AI.
