On the complexity of finding multi-constrained spanning trees

In this paper we present some new results concerning the classification of undirected spanning tree problems from the viewpoint of their computational complexity. Specifically, we study some problems asking for the existence in an undirected, unweighted graph, of a spanning tree satisfying one or several constraints. Thus we extend to the multi-constrained, unweighted case, the analysis that we...

Finding Minimum Congestion Spanning Trees

Given a graph G and a positive integer k, we want to nd k spanning trees on G, not necessarily disjoint, of minimum total weight, such that the weight of each edge is subject to a penalty function if it belongs to more than one tree. We present a polynomial time algorithm for this problem; the algorithm's complexity is quadratic in k. We also present two heuristics with complexity linear in k. ...

MOST – Multiple Objective Spanning Trees Repository Project ♣

This article presents the Multiple Objective Spanning Trees repository – MOST – Project. As the name suggests, the MOST Project intends to maintain a repository of tests for the MOST related problems, mainly addressing real-life situations. MOST is motivated by the scarcity of repositories for the problems in the referred field. This entails difficulty in test and classify the proposed algorith...

Finding the k Smallest Spanning Trees

We give improved solutions for the problem of generating the k smallest spanning trees in a graph and in the plane. Our algorithm for general graphs takes time O(m log β(m,n) + k2); for planar graphs this bound can be improved to O(n+ k2). We also show that the k best spanning trees for a set of points in the plane can be computed in time O(min(k2n + n log n, k2 + kn log(n/k))). The k best orth...

On finding spanning trees with few leaves

The problem of finding a spanning tree with few leaves is motivated by the design of communication networks, where the cost of the devices depends on their routing functionality (ending, forwarding, or routing a connection). Besides this application, the problem has its own theoretical importance as a generalization of the Hamiltonian path problem. Lu and Ravi showed that there is no constant f...
