Random selection of spanning trees on graphs has been treated extensively in technical literature. Popular randomized algorithms have time complexity varying from to , where is the order of a graph, namely, the number of vertices. In this work, we introduce effective and efficient procedures to select spanning trees using random walks with the purpose to balance the diameter of the selected tree, the valencies of its inner vertices, and the number of leaves at its yield. We describe several ways to form transition matrices of Markov chains in terms of probability distributions on the neighborhood of any visited vertex along the random walk.
