6 Directed Graphs
Examples include: a 1-way street one person likes another but the feeling is not necessarily reciprocated a communication channel such as a cable modem that has more capacity for downloading than uploading one entity is larger than another and one job needs to be completed before another job can begin |
What are some examples of directed graphs?
Directed graphs have many applications across a wide range of fields. Here are some examples: Social networks: Social networks are often modeled as directed graphs, where each person is a vertex and relationships such as friendships or following are represented as edges.
What is a directed edge in a V-vertex graph?
We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph. Glossary. Here are some definitions that we use.
What is a directed path in a graph?
A directed walk (or more simply, a walk) in a directed graph G is a sequence of vertices v0, v1, . . . , vk and edges such that vi1 ! vi is an edge of G for all i where 0 i < k. A directed path (or path) in a directed graph is a walk where the nodes in the walk are all different.

Graphs and Digraphs — Examples
A directed acyclic graph (or DAG) is a digraph that has no cycles Example of a DAG: Theorem Every finite DAG has at least one source, and at least one sink In fact, given any vertex v, there is a path from some source to v, and a path from v to some sink |
