Directed vs Undirected Graphs Another important concept in graph theory is the difference between directed and undirected graphs. The previous two examples have demonstrated undirected graphs. As the ...

How Big Data Carried Graph Theory Into New Dimensions Researchers are turning to the mathematics of higher-order interactions to better model the complex connections within their data.

Graph Theory (Basic Concepts) Graph is a non linear data structure, it contains a set of points known as nodes (or vertices) and set of linkes known as edges (or Arcs) which connects the vertices.

This example illustrates the simplest way to use the ODS HTML statement to create an HTML file and a GIF file that you can display in a Web browser. It generates one body file that displays one piece ...

Two graphs that are isomorphic. Back in 1979, two scientists wrote a seminal textbook on computational complexity theory, describing how some problems are hard to solve. The known algorithms for ...

Hard in theory, easy in practice: Why graph isomorphism algorithms seem to be so effective by Andreas Rothe, Institute of Science and Technology Austria Editors' notes ...

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