Strength of three MIP formulations for the prize collecting steiner tree problem with a quota constraint
(Elsevier, 2010-08-01)
This paper investigates the quota version of the Prize Collecting Steiner Tree Problem (PCSTP) on a graph as a generalization of the well-known Steiner tree problem. For this challenging network design problem that arises ...
Tight compact models and comparative analysis for the prize collecting Steiner tree problem
(Elsevier, 2013-03)
We investigate a generalized version of the prize collecting Steiner tree problem (PCSTP), where each node of a given weighted graph is associated with a prize as well as a penalty cost. The problem is to find a tree ...
Algorithmic expedients for the prize collecting Steiner tree problem
(Elsevier, 2010)
This paper investigates the Prize Collecting Steiner Tree Problem (PCSTP) on a graph, which is a generalization of the well-known Steiner tree problem. Given a root node, edge costs, node prizes and penalties, as well as ...
Solving the steiner tree problem with revenues, budget and hop constraints to optimality
(IEEE, 2013)
We investigate the Steiner tree problem with revenues, budget and hop constraints (STPRBH) on graph, which is a generalization of the well-known Steiner tree problem. Given a root node, edge costs, nodes revenues, as well ...
