Graphical steiner tree
WebObviously, every Steiner tree is a k-Steiner tree if kis the number of the terminals. Borchers and Du [4] showed that an optimum k-Steiner tree is a good approximation for a Steiner minimum tree if k is suciently large. Unfortunately, the problem of nding an optimum k-Steiner trees was shown to be NP-hard for k¿4[11]. In this http://profs.sci.univr.it/~rrizzi/classes/Complexity/provette/Santuari/steiner.pdf

In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization.
