Number of spanning Trees
Hi, As all of us knows number of spanning tree of simple labeled graph could be computed by the Kirchhoff's theorem. But is there any other method (other than Brute force) to compute the number of spanning tree of given general graph ? Formula for number ... respectively. If anyone can state simple proof for above mentioned formula then it will great help.

Basic Doubt in spanning tree complexity
Let us say Simple graph has V vertices and E edges. Now i am trying to find relation between E and V. If it is a complete graph ,then E=V(V1)/2, => E=$c.V^2$ => E=$O(V^2)$ => taking log of both sides. => $\log E$=$O(\log V)$ ... .(3) Can someone confirm if the 1 ,2 and the result of them i.e the 3rd equation is valid ?

Graph Theory
Consider a 'reversed Kruskal' Algorithm for computing a MST. Initialize T to be the set of all edges in the graph. Now consider edges from largest to smallest cost. For each edge, delete it from T if that edge belongs to a cycle in T. Assuming all the edge costs are distinct, does this new algorithm correctly compute a MST? a) Yes b) no c) cant say

A fan of order $n$ is a graph on the vertices $\{0, 1, \dots, n\}$ with 2n − 1 edges defined as follows: vertex 0 is connected by an edge to each of the other $n$ vertices, and vertex $i$ ... the number of spanning trees of the fan of order $n$. Calculate $f_4$. Write a recurrence for $f_n$. Solve for fn using ordinary generating fuctions.
