Determine the number of the spanning treess in the following graph ???
Number of Spanning Trees: 2911
This can be solved by Kirchoff's Matrix Tree Theorem :
Make a matrix. (Rows = Columns = Total Vertices)
For i != j , if i & j are adjacent vertices, then M[i][j] = -1, if not M[i][j] = 0 For i == j, M[i][j] = degree of vertex
Last, Calculate the co-factor for any element. The cofactor that you get is the total number of spanning trees for that graph.
