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 with small diameters

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
A spanning tree with small diameter of a graph has many applications. In this paper we first make the following conjecture and show that the condition is best possible if it is true. If a connected graph satisfies , then has a spanning tree with diameter

Pruning a minimum spanning tree [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2012
This work employs some techniques in order to filter random noise from the information provided by minimum spanning trees obtained from the correlation matrices of international stock market indices prior to and during times of crisis. The first technique establishes a threshold above which connections are considered affected by noise, based on the ...

Extensions of the minimum labelling spanning tree problem

open access: yesJournal of Telecommunications and Information Technology, 2006
In this paper we propose some extensions of the minimum labelling spanning tree problem. The main focus is on the minimum labelling Steiner tree problem: given a graph G with a color (label) assigned to each edge, and a subset Q of the nodes of G (basic

Minimum spanning trees [PDF]

open access: yesInvolve, a Journal of Mathematics, 2009
The minimum spanning tree problem originated in the 1920s when O. Borůvka identified and solved the problem during the electrification of Moravia. This graph theory problem and its numerous applications have inspired many others to look for alternate ways of finding a spanning tree of minimum weight in a weighted, connected graph since Borůvka’s time ...

Geo-MST: A geographical minimum spanning tree plugin for QGIS

open access: yesSoftwareX, 2020
Graphs describing the relation between nodes and edges are common in geographic information science. One of the algorithms that operate on graphs is ‘Minimum Spanning Tree (MST)’, which is a tree that connects all the nodes of a graph with minimum cost ...
