WebIn this paper we describe a cutting plane algorithm for the Steiner tree packing problem. We use our algorithm to solve some switchbox routing problems of VLSI-design and report on our computational experience. This includes a brief discussion of separation algorithms, a new LP-based primal heuristic and implementation details.

Webweights are one. Steiner trees are important in various applications such as VLSI routings [32], phylogenetic tree reconstruction [31] and network routing [34]. We refer to the book of Pr¨omel and Steger [38] for an overview of the results and applications of the Steiner tree problem. The Steiner tree problem is known to be NP-hard [26]. http://profs.sci.univr.it/~rrizzi/classes/Complexity/provette/Santuari/steiner.pdf
