A Lagrangean Relaxation Based Algorithm for Solving Set Partitioning Problems

van Krieken, M.G.C; Fleuren, Hein; Peeters, Rene - 2004

In this paper, we discuss a solver that is developed to solve set partitioning problems. The methods used include problem reduction techniques, Lagrangean relaxation and primal and dual heuristics. The optimal solution is found using a branch and bound approach. In this paper, we discuss these...

Problem Reduction in Set Partitioning Problems

van Krieken, M.G.C; Fleuren, Hein; Peeters, Rene - 2004

In this paper, several problem reduction techniques are discussed that can be used to reduce the solution time of set partitioning problems. These techniques can be applied in any solution algorithm for set partitioning problems. Besides a short review of the existing literature on preprocessing...
