WebThe Steiner tree problem is distinguished from the minimum spanning tree (MST) problem (see Section 15.3 (page 484)) in that we are permitted to construct or select intermediate connection points to reduce the cost of the tree. Issues in Steiner tree construction include: • How many points do you have to connect? – The Steiner tree of a pair of WebDec 10, 2007 · In this paper we analyze the problem of designing a truthful mechanism for computing one of the most popular network topologies, i.e. the single‐source shortest paths tree. More precisely, we study several realistic scenarios, in which each agent can own either a single edge or multiple edges of G. udo henss facebook

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.
