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

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

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 ...

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 ...

Minimum-Spanning-Tree-Based Time Delay Estimation Robust to Outliers

open access: yesIEEE Access, 2023
In this paper, we present a novel approach to estimating multiple time delays (TDs) in sensor arrays that is robust to outliers of TD measurements. These measurements are typically obtained from the peak of the cross correlation of two sensor signals but

On the probabilistic min spanning tree Problem [PDF]

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