In graph theory , the degree of a vertex is the number of edges connecting it. In the example below, vertex a has degree 5 , and the rest have degree 1 . A vertex with degree 1 is called an “end vertex” (you can see why).A vertex with degree 1 is called a leaf vertex or end vertex or a pendant vertex, and the edge incident with that vertex is called a pendant edge.A vertex with degree one is called a pendent vertex.
What is a vertex with degree 1?
A vertex with degree 1 is called a leaf vertex or end vertex or a pendant vertex, and the edge incident with that vertex is called a pendant edge.
What is the degree of pendent vertex?
A vertex with degree one is called a pendent vertex.

What are the types of vertex?
Types of vertices
An isolated vertex is a vertex with degree zero; that is, a vertex that is not an endpoint of any edge (the example image illustrates one isolated vertex). A leaf vertex (also pendant vertex) is a vertex with degree one.
Is a 1 vertex graph connected?
A graph with just one vertex is connected. An edgeless graph with two or more vertices is disconnected. A directed graph is called weakly connected if replacing all of its directed edges with undirected edges produces a connected (undirected) graph.
What is Indegree and Outdegree of a graph?
A directed graph with vertices labeled (indegree, outdegree). For a vertex, the number of head ends adjacent to a vertex is called the indegree of the vertex and the number of tail ends adjacent to a vertex is its outdegree (called “branching factor” in trees).
What is Rudrata path?
2. Rudrata Path/Cycle. Input: A graph G. The undirected and directed variants refer to the type of graph. Property: There is a path/cycle in G that uses each vertex exactly once.
What is a sink vertex?
(definition) Definition: A vertex of a directed graph with no outgoing edges. More formally, a vertex with with out-degree 0.

What is node and edge?
The nodes represent different entities (e.g. proteins or genes in biological networks), and edges convey information about the links between the nodes.
What is an odd degree vertices?
A graph vertex in a graph is said to be an odd node if its vertex degree is odd.
What is called vertex?
Definition of vertex
1 : the top of the head. 2a : the point opposite to and farthest from the base in a figure. b : a point (as of an angle, polygon, polyhedron, graph, or network) that terminates a line or curve or comprises the intersection of two or more lines or curves.
How do you find the degree of the vertex?
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 adjacent vertex?
If two vertices in a graph are connected by an edge, we say the vertices are adjacent.

Can a single vertex be called a graph?
Example. In the above shown graph, there is only one vertex ‘a’ with no other edges. Hence it is a Trivial graph.
Is one vertex a path?
In graph theory, a path in a graph is a finite or infinite sequence of edges which joins a sequence of vertices which, by most definitions, are all distinct (and since the vertices are distinct, so are the edges).
Is a single vertex a trail?
Trail is an open walk in which no edge is repeated. Vertex can be repeated. Traversing a graph such that not an edge is repeated but vertex can be repeated and it is closed also i.e. it is a closed trail. Vertex can be repeated.

What is difference between Indegree and Outdegree?
As nouns the difference between outdegree and indegree
is that outdegree is (graph theory) the number of edges directed out of a vertex in a directed graph while indegree is (graph theory) the number of edges directed into a vertex in a directed graph.
What is the degree of node?
The degree of a node is the number of connections that it has to other nodes in the network. In a social network if you have 100 friends then the node that represents you has a degree of 100. Path length is simply the distance between two nodes, measured as the number of edges between them.
What is Hamiltonian path and circuit?
A Hamilton Path is a path that goes through every Vertex of a graph exactly once. A Hamilton Circuit is a Hamilton Path that begins and ends at the same vertex.
What is Hamilton path in graph theory?
In the mathematical field of graph theory, a Hamiltonian path (or traceable path) is a path in an undirected or directed graph that visits each vertex exactly once. A Hamiltonian cycle (or Hamiltonian circuit) is a cycle that visits each vertex exactly once.
What is a semi Hamiltonian graph?
A semi-Hamiltonian graph is a graph that contains a Hamiltonian path, but not a Hamilton cycle.
What is source and sink node?
A node is considered a source in a graph if it has in-degree of 0 (no nodes have a source as their destination); likewise, a node is considered a sink in a graph if it has out-degree of 0 (no nodes have a sink as their source).

What is sink node?
A sink node or a base station is basically a designated device similar to the normal sensor nodes but more powerful. One of the primary tasks of the sink node is to bridge a WSN with the remote users (Fig. 1).
What is a Vertice in a graph?
“Vertex” is a synonym for a node of a graph, i.e., one of the points on which the graph is defined and which may be connected by graph edges. The terms “point,” “junction,” and 0-simplex are also used (Harary 1994; Skiena 1990, p. 80).
