Spanning k-Ended Tree in 2-Connected Graph
Axioms, 2023 Win proved a very famous conclusion that states the graph G with connectivity κ(G), independence number α(G) and α(G)≤κ(G)+k−1(k≥2) contains a spanning k-ended tree. This means that there exists a spanning tree with at most k leaves.

Connectivity index in neutrosophic trees and the algorithm to find its maximum spanning [PDF]
Neutrosophic Sets and Systems, 2020 In this paper, we first define the Neutrosophic tree using the concept of the strong cycle. We then define a strong spanning Neutrosophic tree. In the following, we propose an algorithm for detecting the maximum spanning tree in Neutrosophic graphs. Next,

Successive minimum spanning trees [PDF]
Random Structures & Algorithms, 2021 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.

Clustered Spanning Tree - Conditions for Feasibility [PDF]
Discrete Mathematics & Theoretical Computer Science, 2019 Let H =< V, S > be a hypergraph, where V is a set of vertices and S is a set of not necessarily disjoint clusters Si ⊆ V. The Clustered Spanning Tree problem is to find a spanning tree of G which satisfies that each cluster induces a subtree, when it ...

Breaking intractability of spanning caterpillar tree problem: A logical approach [PDF]
AUT Journal of Mathematics and Computing, 2022 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.

An almost-linear time algorithm for uniform random spanning tree generation [PDF]
Symposium on the Theory of Computing, 2017 We give an m1+o(1)βo(1)-time algorithm for generating uniformly random spanning trees in weighted graphs with max-to-min weight ratio β. In the process, we illustrate how fundamental tradeoffs in graph partitioning can be overcome by eliminating vertices

Degree Sum Condition for the Existence of Spanning k-Trees in Star-Free Graphs
Discussiones Mathematicae Graph Theory, 2022 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.
