The classic algorithm of Dreyfus and Wagner [5] from 1971 solves Steiner Tree on general graphs in time 3n logW jV(G)jO(1), where W is the maximum edge weight in G. For Rectilinear Steiner Tree, an adaptation of Dreyfus-Wagner algorithm provides an algorithm of running time O(n2 3n). The survey of Ganley [7] summarizes the chain of

WebGet Free Course. Named after Jakob Steiner, the Steiner Tree Problem covers a class of problems in combinatorial optimization. Steiner Tree Problems require an optimal interconnect for a given set of objects and a predefined objective function. The Steiner Tree Problem in graphs is one of the variants of this problem. WebThe Steiner Minimal Tree (SMT) Problem: Given a set P of n points, determine a set S of Steiner points such that the minimum spanning tree (MST) cost over P ∪S is minimized. An optimal solution to this problem is referred to as a Steiner minimal tree (or simply “Steiner tree”) over P, denoted SMT(P). northern fcu lowville ny

WebOct 6, 2024 · Abstract. The prize-collecting Steiner tree problem (PCSTP) is a well-known generalization of the classic Steiner tree problem in graphs, with a large number of practical applications. It attracted particular interest during the 11th DIMACS Challenge in 2014, and since then, several PCSTP solvers have been introduced in the literature.
