Engineers could use this breakthrough in graph theory to design wildly efficient quantum computer chips. By Sarah Wells Published: Mar 01, 2021 5:26 PM EST. Getty/Photo Illustration by PM.

Graph theory serves as a powerful tool for modeling the complexity of the Web. Chayes and Borgs have shown how the patterns formed by links fanning out from spam sites differ in appearance from ...

“A graph is a good abstraction for a social network, but social networks are so much more. With higher-order systems, there are more ways to model.” Graph theory may show how individuals are connected ...

Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

Work disproving a 1995 theorem in graph theory has earned UBC mathematician Dr. Stephanie van Willigenburg and colleagues the 2023 David P. Robbins Prize. In its simplest form, graph theory involves ...
