Web1. nov 2024 · A review on algorithms for generating STs is Algorithms for generating all possible spanning trees of a simple undirected connected graph: an extensive review. A lot of the methods use a BFS to generate an initial ST; all other STs can then be generated from this initial ST. I recommend taking a look at the review.

Motivation: competitive programming problem … WebThe number t(G) of spanning trees of a connected graph is a well-studied invariant.. In specific graphs. In some cases, it is easy to calculate t(G) directly: . If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.
