✦ Synopsis


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 dynamic data structures developed to speed up the algorithm. Computational results on new randomly generated instances and on instances taken from the literature indicate that the proposed approach produces high-quality solutions within reasonable computing times.

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 Steiner Tree Problem (STP) in graphs is a well-known NP-hard problem. It has regained attention due to the introduction of new telecommunication technologies, such as ATM, since it appears as the inherent mathematical structure behind multicast communications.

The Capacitated Minimum Spanning Tree Problem (CMSTP) is to find a minimum spanning tree subject to an additional constraint stating that the number of nodes in each subtree pending from a given root node is not greater than a given number Q.

The degree-constrained spanning tree problem is of high practical importance. Up to now, there are few effective algorithms to solve this problem because of its NP-hard complexity. In this paper, we present a new approach to solve this problem by using genetic algorithms and computational results to
