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
