I think the problem is just counting spanning trees
Any more good resources to understand the algorithm ? Thanks a lot for giving the link of algorithm .
Just try Googling "counting spanning trees," or "Kirchoff's theorem" and there are a lot of sources. Here's a proof, and here's how to find a determinant
Thanks a lot ! I will try my best to solve the problem .
Thanks a lot . Finally I solved the problem !
