Steiner tree

(definition)

Definition: A minimum-weight tree connecting a designated set of vertices, called terminals, in an undirected, weighted graph or points in a space. The tree may include non-terminals, which are called Steiner vertices or Steiner points.

Specialization (... is a kind of me.)
Euclidean Steiner tree, rectilinear Steiner tree.

See also minimum spanning tree.

Note: This differs from the minimum spanning tree in that the set of Steiner vertices must be identified. That is, additional vertices may be used.

Named for Jakob Steiner.

Some authors distinguish between Steiner trees and minimum Steiner trees.

Author: JLG

Implementation

(C and Pascal), GeoSteiner (C) - software for computing steiner trees.
