The terminals are the given vertices which must be included in the solution. The cost of a Steiner tree is defined as the total edge weight. A Steiner tree may contain some nonterminal vertices to reduce the cost.

Steiner minimal trees book consists of a tree, known as the Steiner Minimal Tree (SMT). The nodes of an SMT are the terminals and possibly additional points, called Steiner points, and the length of the tree is measured by the sum of the Euclidean distances between adjacent nodes.

If no Steiner points were allowed in the solution, the. The 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).Cited by: () Euclidean Steiner minimal trees, minimum energy configurations, and the embedding problem of weighted graphs in E3.

A Steiner minimal tree is always a Steiner tree, and a Steiner tree is always a relatively minimal tree foi its topology.

The resulting interconnection, a Steiner minimal tree (SMT), can be decomposed into its full Steiner trees by splitting its inner terminals (a full Steiner tree (FST) is a tree with no inner terminals, i.e., all terminals have degree 1).

The FST approach consists of two by: The Steiner problem asks for a shortest network which spans a given set of points. Minimum spanning networks have been well-studied when all connections are required to be between the given points.

The novelty of the Steiner tree problem is that new auxiliary points can be introduced between the original points. The total distance of all edges of this Steiner tree is at most 2(/l) times that of a Steiner minimal tree, where l is the minimum number of leaves in any Steiner minimal tree.

Spanning Tree vs Steiner Tree Minimum Spanning Tree is a minimum weight tree that spans through all vertices.

If given subset (or terminal) vertices is equal to set of all vertices in Steiner Tree problem, then the problem becomes Minimum Spanning Tree problem.4/5. The Minimal Spanning Trees activity explored techniques for finding efficient networks between points.

Steiner trees are another way to approach the same problem, and they can be used to find even more efficient networks. This is another tough problem from computer science, converted into an activity which is easy to explain, with variations suitable for higher-level.

In a few special cases, Steiner’s problem can be solved exactly. For a regular polygon with six or more sides, the polygon itself (less one edge) is the solution: the Steiner minimal tree coincides with the minimal spanning tree; no additional Steiner points are required.
