Local Degree
The degree of a Vertex of a Graph is the number of Edges whichtouch the Vertex, also called the Local Degree. The Vertex degree of a point 
in aGraph, denoted 
, satisfies
where
is the total number of Edges. Directed graphs have two types of degrees, known as the Indegree andOutdegree.See also Indegree, Outdegree- s-Additive Sequence
