You’d just go through the vertices one by one, examining their connections. As the graph gets bigger, the time it takes to do this increases slowly, in what’s called polynomial time. As a result, a ...

He was later able to shrink the graph to 1,581 vertices and do a computer check to verify that it was not four-colorable. The discovery of any graph that requires five colors was a major ...

Chien will lead a team of University of Chicago computer science researchers ... networks that contain billions or trillions of vertices and edges. “Efficient and scalable computation over massive ...
