Given two ordered trees S S and T T, the tree inclusion problem is to determine whether it is possible to obtain S S from T T by deleting nodes. Recently, this problem has been recognized as an important primitive in query processing for Ε½< Ε½ .< < <. structured text databases. In this paper we prese

In this paper, we consider the inverse spanning tree problem. Given an undi-0 Ε½ 0 0 . rected graph G s N , A with n nodes, m arcs, an arc cost vector c, and a spanning tree T 0 , the inverse spanning tree problem is to perturb the arc cost vector c to a vector d so that T 0 is a minimum spanning tre
We consider dual approaches for the Shortest Path Tree problem. After a brief introduction to the problem, we review the most important dual algorithms which have been described in the literature for its solution and propose a new family of dual ascent algorithms. In these algorithms, ''local'' and
The most common problems studied in network location theory are the p-median and the p-center models. The p-median problem on a network is concerned with the location of p points (medians) on the network, such that the total (weighted) distance of all the nodes to their respective nearest points is
The group Steiner tree problem is a generalization of the Steiner tree problem where we are given several subsets (groups) of vertices in a weighted graph, and the goal is to find a minimum-weight connected subgraph containing at least one vertex from each group.The problem was introduced by Reich a
The Capacitated Shortest Spanning Tree Problem consists of determining a shortest spanning tree in a vertex weighted graph such that the weight of every subtree linked to the root by an edge does not exceed a prescribed capacity. We propose a tabu search heuristic for this problem, as well as dynami
