Forbes contributors publish independent expert analyses and insights. I help people communicate data clearly with graphs. This article is more than 10 years old. This is the first post in a new blog ...

We introduce the notion of the L-core of a graph what enables a simple description of some properties of the eigenspace of the eigenvalue — 2 in generalized line graphs and an elegant formulation of ...

In 1950 Edward Nelson, then a student at the University of Chicago, asked the kind of deceptively simple question that can give mathematicians fits for decades. Imagine, he said, a graph — a ...

Graph partitioning and bisection problems occupy a central position in combinatorial optimisation and theoretical computer science. These issues involve dividing a graph’s vertex set into distinct ...

Microsoft Excel doesn't always provide everything you need when it generates graphs. For example, by default, your line graph doesn't included a title. However, this doesn't mean you have to go ...

Graph optimisation problems encompass a diverse range of challenges aimed at finding optimal or near‐optimal solutions in networks or graphs. These problems are pivotal in areas such as communication ...

A puzzle that has long flummoxed computers and the scientists who program them has suddenly become far more manageable. A new algorithm efficiently solves the graph isomorphism problem, computer ...
