WebThe Steiner Minimal Tree (SMT) Problem: Given a set P of n points, determine a set S of Steiner points such that the minimum spanning tree (MST) cost over P ∪S is minimized. An optimal solution to this problem is referred to as a Steiner minimal tree (or simply “Steiner tree”) over P, denoted SMT(P). WebTo prove this, we’re going to show that approximating Metric Steiner Tree of (V;c0;T) is just as good as approximating Steiner tree on (G;c;T). Let’s start with the trivial direction.
