Theoretical computer scientists are normally a fairly sedate bunch, but are humming with excitement after a potential breakthrough in a long-standing problem called graph isomorphism. The result ...

The study of such graphs is called graph theory. Engineers need to find planarity in a graph when, for example, they are designing a computer chip without a crossed wire.

The back and forth concerns the graph isomorphism problem, which asks when two different-looking graphs — networks of nodes and edges — have the same underlying connectivity. Despite how simple the ...

About graph theory. A GRAPH is a very simple construction used to model things that can be described as objects and the connections between them. ... Could be used for computer electronics .

“It’s a great algorithm,” said Erik Demaine, a computer scientist at the Massachusetts Institute of Technology.“It’s very fast, simple and easy to implement.” To put this procedure into practice, ...

Graphs are relatively simple mathematical objects — abstract representations of networks — that arise frequently in physics, chemistry and computer science.
