WebApr 1, 1993 · Even though the Steiner Tree problem has already been investigated intensively in the last decades, it might be further optimized with the help of new computing paradigms and emerging approaches. 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

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. While Steiner tree problems may be formulated in a number of settings, they all require an optimal interconnect for a given set of objects and a predefined objective function.
