New proof in graph theory, the math behind network behavior

Originally invented by Leonhard Euler in 1735, graph theory deals with the nodes and connecting lines that comprise networks—such as the interstate highway system, the power grid, and even social networks. Better understanding of the mathematical fundamentals underlying modern networks may lead to advances in cyber security, cryptography, and network analysis.
