A graph database is a dynamic database management system uniquely structured to manage complex and interconnected data.

Certain graph problems, like finding subsets of highly connected nodes called cliques, fall into a class known as NP-complete and may be difficult to solve efficiently.

To understand what a time graph is showing you, you need to look at three things: 1. Title - The title tells you what the graph is about. For example, "Temperature on the First of September." 2.

But start with a complete graph of six vertices, and now there’s no way to color the edges with two colors without creating a monochromatic clique of at least three vertices. Or, to put it another way ...

A new algorithm efficiently solves the graph isomorphism problem, ... The traveling salesman problem (SN Online: 2/20/12) is among the NP-complete puzzles. Graph isomorphism falls in between.
