The field of graph theory has been around since 1736, when Leonhard Euler published an article on the subject of the Seven Bridges of Königsberg (in Prussia, today’s Kaliningrad in Russia).

Sudoku and Graph Theory. Mathematicians find new clues to the popular puzzle. By Julie Rehmeyer. July 3, 2007 at 4:39 pm - More than 2 years ago. Share this: Share via email (Opens in new window ...

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 ...

“There are still many open questions there,” Benson said. “Some of these impossibility results are interesting because you can’t possibly reduce them to graphs. And on the theory side, if you haven’t ...

The study of such graphs is called graph theory. Engineers need to find planarity in a graph when, for example, they are designing a computer chip without a crossed wire.

Traffic density estimation plays a crucial role in traffic management. This paper introduces a novel approach for accurately estimating traffic density using a graph-based density estimation algorithm ...

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.
