## Can a vertex have more than one edge?

In mathematics, and more specifically in graph theory, a multigraph is a graph which is permitted to have multiple edges (also called parallel edges), that is, edges that have the same end nodes. Thus two vertices may be connected by more than one edge.

## What is Page Rank in NodeXL?

PageRank is a link analysis algorithm that scores the relative importance of Web pages in a hyperlinked Web network, such as the WWW, using eigenvector analysis. The PageRank of a Web page is defined recursively; a page has a high importance if it has a large number of incoming links from highly important Web pages.

**What are vertices in NodeXL?**

This is an overview of Overall Graph Metrics shown in the Overall Metrics spreadsheet of NodeXL and on the network report pages in NodeXL Graph Gallery. A vertex is an element of a network. The vertices count is the number of people or things in the network. An edge is a connection between two vertices.

**Is a path that begins and ends at the same vertex?**

A circuit is path that begins and ends at the same vertex. A circuit that doesn’t repeat vertices is called a cycle. A graph is said to be connected if any two of its vertices are joined by a path.

### What is PageRank Gephi?

The Page Rank concept is a way in which a web page or social network node can be given an “importance score”. The Page Rank score for a given page/node is based on the links made to that said page/node from other pages/nodes. The links to a given page/node are called the backlinks/in-degrees for that page/node.

### How is the reciprocated vertex pair ratio defined?

Reciprocated Vertex Pair Ratio When two vertices both link to each other their connection is “reciprocated”. This is the percentage of vertices that have a reciprocal relationship. When an edge from A to B is joined by another edge from B to A then their connection is “reciprocated”.

**What does it mean when two vertices have a reciprocal relationship?**

When two vertices both link to each other their connection is “reciprocated”. This is the percentage of vertices that have a reciprocal relationship. When an edge from A to B is joined by another edge from B to A then their connection is “reciprocated”. This is the percentage of edges that have a reciprocal relationship.

**How is the graph in NodeXL laid out?**

The graph was laid out using the Harel-Koren Fast Multiscale layout algorithm. Data Import : The graph represents a network of 1,934 Twitter users whose tweets in the requested range contained “dhinchcliffe”, or who were replied to or mentioned in those tweets.

#### What is the vertex count in a network?

A vertex is an element of a network. The vertices count is the number of people or things in the network.
