Another important concept in graph theory is the difference between directed and undirected graphs. The previous two examples have demonstrated undirected graphs. As the name implies, the edges in an ...

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.

Graph isomorphism is a subset of string isomorphism; in fact, string isomorphism is the subject of Babai’s paper, although it mainly discusses graphs. While there had been solutions for various ...
