On the Role of Partition Inequalities in Classical Algorithms for Steiner Problems in Graphs
(University of Waterloo, 2006)The Steiner tree problem is a classical, well-studied, $\mathcal{NP}$-hard optimization problem. Here we are given an undirected graph $G=(V,E)$, a subset $R$ of $V$ of terminals, and non-negative costs $c_e$ for all ...
