Let T be a weighted rooted tree of k levels such that (1) the vertices in level j have a degree equal to d k-j +1 for j = 1, 2, . . . , k, and (2) the edges joining the vertices in level j with the vertices in level (j + 1) have a weight equal to w k-j for j = 1, 2, . . . , k -1. We give a complete
