The Spanning Tree of a Divisible Multiple Graph
Моделирование 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
AKCE 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
Journal 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

Balanced Partition of Minimum Spanning Trees [PDF]
International Journal of Computational Geometry & Applications, 2002 To better handle situations where additional resources are available to carry out a task, many problems from the manufacturing industry involve dividing a task into a number of smaller tasks, while optimizing a specific objective function. In this paper we consider the problem of partitioning a given set [Formula: see text] of n points in the plane ...

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

A MINIMUM SPANNING TREE BASED METHOD FOR UAV IMAGE SEGMENTATION [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 This paper proposes a Minimum Span Tree (MST) based image segmentation method for UAV images in coastal area. An edge weight based optimal criterion (merging predicate) is defined, which based on statistical learning theory (SLT).
