Describe and analyze backtrack algorithm for listing . all spanning trees. Time requirement: polynomial in |V|, |E| and linear in |T|. A . tree. is a connected undirected graph with no simple circuits.. Since a tree cannot have a simple circuit, a tree cannot contain multiple edges or loops.. Therefore, any tree must be a . simple graph. Scaling Networks.
