The constrained minimum spanning tree problem [PDF]

open access: possible, 1996
Given an undirected graph with two different nonnegative costs associated with every edge e (say, we for the weight and l e for the length of edge e) and a budget L, consider the problem of finding a spanning tree of total edge length at most L and minimum total weight under this restriction.

Minimum Spanning Trees

2010
In this chapter, we study the behavior of stochastic search algorithms on an important graph problem. We consider the well-known problem of computing a minimum spanning tree in a given undirected connected graph with n vertices and m edges. The problem has many applications in the area of network design.

Minimum Spanning Trees [PDF]

open access: possible, 2004
Suppose you have a business with several branch offices and you want to lease phone lines to connect them with each other. Your goal is to connect all your offices with the minimum total cost. The resulting connection should be a spanning tree since if it is not a tree, you can always remove some edges without losing the connectivity to save money.

Minimum Spanning Tree [PDF]

open access: possible, 1999
The case studies usually found in the B literature present many of the characteristics common to safety-critical software systems. The successful use of B on such systems, as exemplified by several realistic large-size projects [21, 40], has greatly contributed to increasing the interest of industrial practitioners in formal development techniques.

On Steiner trees and minimum spanning trees in hypergraphs

Operations Research Letters, 2003
The bottleneck of the state-of-the-art algorithms for geometric Steiner problems is usually the concatenation phase, where the prevailing approach treats the generated full Steiner trees as edges of a hypergraph and uses an LP-relaxation of the minimum spanning tree in hypergraph (MSTH) problem.

Finding Minimum Spanning Trees

SIAM Journal on Computing, 1976
This paper studies methods for finding minimum spanning trees in graphs. Results include 1. several algorithms with $O(m\log \log n)$ worst-case running times, where n is the number vertices and m is the number of edges in the problem graph; 2. an $O(m)$ worst-case algorithm for dense graphs (those for which m is $\Omega (n^{1 + \varepsilon } )$ for ...

Reoptimization of the minimum spanning tree

WIREs Computational Statistics, 2011
AbstractWe implement a fast reoptimization algorithm for MIN SPANNING TREE under vertex insertions, initially proposed and analyzed in the work of Boria and Paschos [Boria N, Paschos VTh. Fast reoptimization for the minimum spanning tree problem. J Discrete Algor 2010, 8:296–310] and study its experimental approximation behavior in randomly generated ...

Minimum Spanning Trees

2013
A minimum spanning tree of a weighted graph is its spanning tree T with a minimum total cost of edges in T of all possible spanning trees. Minimum spanning trees have many applications in computer networks. In this chapter, we investigate synchronous and asynchronous distributed algorithms to construct minimum spanning trees.
