In this paper, we review recent work on the minimum labeling spanning tree problem and obtain a new worst-case ratio for the MVCA heuristic. We also present a family of graphs in which the worst-case ratio can be attained. This implies that the new ratio cannot be improved any further.

Given a simple rectilinear polygon P with k sides and n terminals on its boundary, we present an O(k 3 n)-time algorithm to compute the minimal rectilinear Steiner tree lying inside P interconnecting the terminals. We obtain our result by proving structural properties of a selective set of minimal S
In this paper we present an RNC approximation algorithm for the Steiner tree problem in graphs with performance ratio 5r3 and RNC approximation algorithms for the Steiner tree problem in networks with performance ratio 5r3 q β for all β ) 0. This is achieved by considering a related problem, the min
