Determining hop-constrained spanning trees with repetitive heuristics

open access: yesJournal of Telecommunications and Information Technology, 2023
The hop-constrained minimum spanning tree problem is the problem of determining a rooted spanning tree of minimum cost in which each path from the root node to any other node contains at most H hops or edges.

The spanning k-trees, perfect matchings and spectral radius of graphs [PDF]

open access: yesLinear and multilinear algebra, 2021
A k-tree is a spanning tree in which every vertex has degree at most k. In this paper, we provide a sufficient condition for the existence of a k-tree in a connected graph with fixed order in terms of the adjacency spectral radius and the signless ...

On the probabilistic min spanning tree Problem [PDF]

open access: yes, 2010
We study a probabilistic optimization model for min spanning tree, where any vertex vi of the input-graph G(V,E) has some presence probability pi in the final instance G′ ⊂ G that will effectively be optimized.

Spanning trees in a cactus

open access: yesDiscrete Mathematics, 1992
The paper studies spanning trees of a cactus. A cactus is a connected graph in which each block is either an edge or a circuit. A rooted graph is an ordered pair \((G,R)\), where \(G\) is a graph and \(R\) is a set of its vertices which contains exactly one vertex from each connected component of \(G\).

The Spanning Tree of a Divisible Multiple Graph

open access: yesМоделирование и анализ информационных систем, 2018
In this paper, we study undirected multiple graphs of any natural multiplicity k > 1. There are edges of three types: ordinary edges, multiple edges and multi-edges.

Spanning Trees and bootstrap reliability estimation in correlation based networks [PDF]

open access: yes, 2006
We introduce a new technique to associate a spanning tree to the average linkage cluster analysis. We term this tree as the Average Linkage Minimum Spanning Tree.

Spanning tree protokol

open access: yesPolytechnic and design, 2019
A campus network is an enterprise network that consist of many connected LANs that are all usually in the same geographic area. According to the Network Hierarchy, a campus network has three separated layers - Access Layer, Distribution Layer and Core Layer.

Degree-Constrained k-Minimum Spanning Tree Problem

open access: yesComplexity, 2020
Let GV,E be a simple undirected complete graph with vertex and edge sets V and E, respectively. In this paper, we consider the degree-constrained k-minimum spanning tree (DCkMST) problem which consists of finding a minimum cost subtree of G formed with ...

On Minimum Average Stretch Spanning Trees in Polygonal 2-trees [PDF]

open access: yes, 2014
A spanning tree of an unweighted graph is a minimum average stretch spanning tree if it minimizes the ratio of sum of the distances in the tree between the end vertices of the graph edges and the number of graph edges.
