Breaking intractability of spanning caterpillar tree problem: A logical approach [PDF]
In this paper we pursue a logical approach to prove that the optimisation problem of finding a spanning caterpillar tree in a graph has polynomial algorithm for bounded tree width graphs.

Successive minimum spanning trees [PDF]
AbstractIn a complete graphwith independent uniform(or exponential) edge weights, letbe the minimum‐weight spanning tree (MST), andthe MST after deleting the edges of all previous trees. We show that each tree's weightconverges in probability to a constant, with, and we conjecture that.

End‐faithful spanning trees in graphs without normal spanning trees [PDF]
AbstractSchmidt characterised the class of rayless graphs by an ordinal rank function, which makes it possible to prove statements about rayless graphs by transfinite induction. Halin asked whether Schmidt's rank function can be generalised to characterise other important classes of graphs. In this paper, we address Halin's question: we characterise an

Degree Sum Condition for the Existence of Spanning k-Trees in Star-Free Graphs
For an integer k ≥ 2, a k-tree T is defined as a tree with maximum degree at most k. If a k-tree T spans a graph G, then T is called a spanning k-tree of G.

Streaming Complexity of Spanning Tree Computation [PDF]
The semi-streaming model is a variant of the streaming model frequently used for the computation of graph problems. It allows the edges of an n-node input graph to be read sequentially in p passes using Õ(n) space.

Degree-Constrained k-Minimum Spanning Tree Problem
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 ...

Isolation Forest Based on Minimal Spanning Tree
Detecting anomalies in data sets has been one of the most studied issues in modern data analysis. Therefore, there is a plethora of applications in a very wide range of fields of science and technology.

On the probabilistic min spanning tree Problem [PDF]
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.

The Spanning Tree of a Divisible Multiple Graph
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]
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.
