WebAs it is a directed graph, each edge bears an arrow mark that shows its direction. Note that in a directed graph, ‘ab’ is different from ‘ba’. Simple Graph. A graph with no loops and no parallel edges is called a simple graph. The maximum number of edges possible in a single graph with ‘n’ vertices is n C 2 where n C 2 = n(n – 1)/2. http://web.mit.edu/neboat/Public/6.042/graphtheory3.pdf
