WebSolution 3 Let’s first understand Steiner Trees a little better and see if we can find one in the following graph with R= {A,D,F} and C=34. We have included A, D, and F in the tree, but we also needed to include C and E. The total cost is 33, which is less than 34, so we have found a Steiner tree with the given constraints.
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.
