In graph theory, “planar” means that a graph can be embedded in the plane in such a way that its edges never cross. De Grey’s graph is instead a graph in the plane with edges of unit length, or just a ...

How to plot your graph. A distance/time graph shows time on one axis (x) and distance on the other axis (y). It is important to plot the important information from the problem.

This guarantees that every graph has an even subgraph that’s at least half as big as the original. But how big an odd subgraph can be has been an open research question in graph theory for over 60 ...

Graphs are everywhere. ... In theory, it cannot be ruled out that the algorithms might run for longer than the age of the ...

Graph theory isn’t enough.. The mathematical language for talking about connections, which usually depends on networks—vertices (dots) and edges (lines connecting them)—has been an ...
