We give a tight analysis of the greedy algorithm introduced by Krumke and Wirth for the minimum label spanning tree problem. The algorithm is shown to be a (ln(n -1) + 1)-approximation for any graph with n nodes (n > 1), which improves the known performance guarantee 2 ln n + 1.

The distance between a pair of vertices u, u in a graph G is the length of a shortest path joining u and u. The diameter diam(G) of G is the maximum distance between all pairs of vertices in G. A spanning tree Tof G is diameter preserving if diam(T) = diam(G). In this note, we characterize graphs th
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
