The clustering coefficient for a vertex is the proportion of links between the vertices within its neighborhood divided by the number of links that could possibly exist between them. In this situation, the clustering coefficient of each node would be calculated as below: Node 2: a) N(2) = {V6, V10, V15, V17, V18, V19} b) 18 Possible Edges c) 10 Connected Edges d) C = 10 / 18 Node 8: a) N(8) = {V6, V9, V12, V15, V18, V20} b) 22 Possible Edges c) 11 Connected Edges d) C = 11 / 22 Node 13: a) N(13) = {V5, V9, V11, V12, V14, V16} b) 21 Possible Edges c) 13 Connected Edges d) C = 13 / 21...
