steiner tree problem
Implications, conflicts, and reductions for Steiner trees
The Steiner tree problem in graphs (SPG) is one of the most studied problems in combinatorial optimization. In the last 10 years, there have been significant advances concerning approximation and complexity of the SPG. However, the state of the art in (practical) exact solution of the SPG has remained largely unchallenged for almost 20 years. … Read more
Optimal Steiner Trees Under Node and Edge Privacy Conflicts
In this work, we suggest concepts and solution methodologies for a series of strategic network design problems that find application in highly data-sensitive industries, such as, for instance, the high-tech, governmental, or military sector. Our focus is on the installation of widely used cost-efficient tree-structured communication infrastructure. As base model we use the well-known Steiner … Read more
