With applications in communication networks, the minimum stretch spanning tree problem is to find a spanning tree T of a graph G such that the maximum distance in T between two adjacent vertices is minimized.

Prim's algorithm, discovered in 1930 by mathematicians, Vojtech Jarnik and Robert C. Prim, is a greedy algorithm that finds a minimum spanning tree for a connected weighted graph. It finds a tree of that graph which includes every vertex and the total weight of all the edges in the tree is less than or equal to every possible spanning tree. We also investigate the problem of finding short trees and, more generally, that of finding networks with minimum diameter. A simple technique is used to provide a polynomial-time solution for finding k -trees of minimum diameter. We identify easy and hard problems arising in finding short networks using a framework due to T. C. Hu. Keywords.

A rooted spanning tree of a directed graph is a rooted tree containing edges of the graph such that every vertex of the graph is an endpoint of one of the edges in the tree. $$. To get a spanning tree for G ¯ you will need a spanning tree for K 7 and a spanning tree for K 8. They will then be joined into a single tree by the edge connecting the two parts of the graph. If a graph is a complete graph with n vertices, then total number of spanning trees is n n − 2, right? So the number of spanning trees of G ¯ will be. The restrictions to the 0-white/open regions of the continuum tree paths correspond to the scaling limit of the forest F (= Fδ ), while the minimal G- spanning tree converges in the scaling limit to a minimal “cluster connecting tree ,” i.e., a minimal spanning tree in the “graph” whose vertices are the continuum 0-white regions and whose edges are the marked double points. With applications in communication networks, the minimum stretch spanning tree problem is to find a spanning tree T of a graph G such that the maximum distance in T between two adjacent vertices is minimized.
