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 ...

Two computer scientists found — in the unlikeliest of places — just the idea they needed to make a big leap in graph theory. This past October, as Jacob Holm and Eva Rotenberg were thumbing through a ...

The transitive closue of a directed, acyclic graph can be casually defined as the "reachability matrix" of any given graph. That is, a matrix in which the intersection of any two vertices is either 0, ...

Computer scientists are abuzz over a fast new algorithm for solving one of the central problems in the field. (January 15, 2017, update: On January 4, Babai retracted his claim that the new algorithm ...

This repository presents a comprehensive analysis of airline route networks using graph theory and advanced shortest path algorithms. The project implements Johnson's algorithm to identify optimal ...

Like the core algorithm, Google’s Knowledge Graph periodically updates. But little has been known about how, when, and what it means — until now. I believe these updates consist of three things: ...
