Back in the hazy olden days of the pre-2000s, navigating between two locations generally required someone to whip out a paper map and painstakingly figure out the most optimal route between those ...

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 ...

I'm tasked to write a layout panel and library to display a directional left-right graph with a single source and sink node. Most of the documents I'm finding online are heavily detailed on the theory ...

Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a ...

I have a 2D graph that I'm trying to lay out cleanly. Does anyone know of an algorithm that, given the x, y position of every node and the graph's edges will tell me how many edges cross. Right now I ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

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 ...

GraphViz is a collection of tools for manipulating graph structures and generating graph layouts. Graphs can be either directed or undirected. GraphViz offers both graphical and command-line tools. A ...
