How do you find the degree of a graph?
To analize a graph it is important to look at the degree of a vertex.
One way to find the degree is to count the number of edges which has that vertx as an endpoint.
An easy way to do this is to draw a circle around the vertex and count the number of edges that cross the circle.What is the average degree of a directed graph?
For a directed graph, each edge accounts to 1 degree, and not two (as the edges grant a degree just to one vertex, and not two vertices).
Therefore, for a directed graph, the average degree is simply the number of edges divided by the number vertices.What is average degree?
Average degree is simply the average number of edges per node in the graph.
It is relatively straightforward to calculate.
Total Edges/Total Nodes=Average Degree.Returns the average degree of the neighborhood of each node.
In an undirected graph, the neighborhood N(i) of node i contains the nodes that are connected to i by an edge.
