A graph can have multiple root vertices. For example, each vertex in astrongly connected componentis a root vertex. In such cases, the solution should return anyone of them. If the graph has no root vertices, the solution should return-1. The root vertex is4since it has a path to every...
( G ) ≤ cdim ( G ) ≤ cdim G ( v ) ≤ | V ( G ) | 1 for any vertex v of G , we show the existence of a pair ( G , v ) such that cdim G ( v ) takes all positive integer values from dim ( G ) to | V ( G ) | 1 , as v varies in a fixed graph G . ...
Degree of Vertex of a Graph - It is the number of vertices adjacent to a vertex V. Notation − deg(V). In a simple graph with n number of vertices, the degree of any vertices is − deg(v) = n – 1 ∀ v ∈ G A vertex can form an edge with all other
The degree of a graph vertex v of a graph G, also called the vertex degree or local degree, is the number of graph edges which touch v. The vertex degrees are illustrated above for a random graph. The vertex degree is also called the local degree or vale

1. This work examines different notions of similarity on the vertex set VG of a graph G. Some notions are perhaps less natural than others, but all of them have a certain interest, be it purely the...
vertex coverof a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. Now given a graph with several vertex sets, you are supposed to tell if each of them is a vertex cover or not. ...
