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.

WebNov 10, 2024 · The term Steiner tree problem on graphs encompasses a class of graph problems that all ask to connect speci c vertices of a graph, so-called terminals, at minimum cost. Connecting the vertices usually requires to select edges of a given graph that form a tree and the resulting solution is called a Steiner tree. 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
