In this paper, we study the Node Weighted Steiner Tree Problem (NSP). This problem is a generalization of the Steiner tree problem in the sense that vertex weights are considered. Given an undirected graph, the problem is to find a tree that spans a subset of the vertices and is such that the total

Let L(T) be the closed-set latice of a tree T. The lower length l, (L(T)) of L (T) is defined as Call a set S of vertices in T a sparse set if d(x, y)/> 3 for any two distinct vertices x, y in S. The sparsity y(T) of T is defined as y(T) = max {Isl: s is a sparse set of T}. We prove that, for any
