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.

WebThe Steiner tree problem has been determined to be an NP-complete problem. There are a number of approximation algorithms for the Steiner tree problem. In this section, we discuss a well-known approximation algorithm developed by Kou, Markowsky, and Berman in 1981 [461], which we will refer to as the KMB algorithm. Webized Steiner problem is O(log2 n) competitive. An ›(logn) lower bound on the competitiveness of any on-line algorithm for the generalized Steiner problem follows from the lower bound for on-line Steiner tree, shown by Imaze and Wax-man [IW91]. Following this work, Berman and Coulston [BC97] gave a diﬁer-
