Algorithms for the Maximum Weight Connected Subgraph and Prize-collecting Steiner Tree Problems
نویسندگان
چکیده
We present new exact and heuristic algorithms for the prizecollecting Steiner tree problem. The exact algorithm rst reduces the size of the input graph while preserving equivalence of the optimal solutions and then uses mixed integer linear programming to solve the resulting instance. For our heuristic, we reduce the size of the instance graph further, but without guaranteeing the equivalence of the optimal solutions and then use the same integer linear programming based approach to solve the remaining instance.

Transformations for the Prize-Collecting Steiner Tree Problem and the Maximum-Weight Connected Subgraph Problem to SAP
Transformations of Steiner tree problem variants have been frequently discussed in the literature. Besides allowing to easily transfer complexity results, they constitute a central pillar of exact state-of-the-art solvers for well-known variants such as the Steiner tree problem in graphs. In this paper transformations for both the prize-collecting Steiner tree problem and the maximum-weight con...
متن کاملReduction Techniques for the Prize-Collecting Steiner Tree Problem and the Maximum-Weight Connected Subgraph Problem
The concept of reduction has frequently distinguished itself as a pivotal ingredient of exact solving approaches for the Steiner tree problem in graphs. In this paper we broaden the focus and consider reduction techniques for three Steiner problem variants that have been extensively discussed in the literature and entail various practical applications: The prize-collecting Steiner tree problem,...
متن کاملA dual-ascent-based branch-and-bound framework for the prize-collecting Steiner tree and related problems
In this work we present a branch-and-bound (B&B) framework for the asymmetric prizecollecting Steiner tree problem (APCSTP). Several well-known network design problems can be transformed to the APCSTP, including the Steiner tree problem (STP), prize-collecting Steiner tree problem (PCSTP), maximum-weight connected subgraph problem (MWCS) and the nodeweighted Steiner tree problem (NWSTP). The ma...
متن کاملThe Maximum Weight Connected Subgraph Problem
The Maximum (Node-) Weight Connected Subgraph Problem (MWCS) searches for a connected subgraph with maximum total weight in a node-weighted (di)graph. In this work we introduce a new integer linear programming formulation built on node variables only, which uses new constraints based on node-separators. We theoretically compare its strength to previously used MIP models in the literature and st...
متن کاملA 4-Approximation Algorithm for k-Prize Collecting Steiner Tree Problems
This paper studies a 4-approximation algorithm for k-prize collecting Steiner tree problems. This problem generalizes both k-minimum spanning tree problems and prize collecting Steiner tree problems. Our proposed algorithm employs two 2-approximation algorithms for k-minimum spanning tree problems and prize collecting Steiner tree problems. Also our algorithm framework can be applied to a speci...
