Pricing the multiple-choice nested knapsack problem
Drexl, Andreas; Jørnsten, Kurt - 2007
The multiple-choice nested knapsack problem (MCKP) is a generalization of the ordinary knapsack problem, where the set of items is partitioned into classes. The binary choice of selecting an item is replaced by taking exactly one item out of each class of items. Due to the fact that the MCKP is...

Combinatorial optimisation problems of the assignment type and a partitioning approach
Klose, Andreas; Drexl, Andreas - 2001
Assignment type problems consist in optimally assigning or allocating a given set of "activities" to a given set of "resources". Optimisation problems of the assignment type have numerous applications in production planning and logistics. A popular approach to solve such problems or to compute...

Round robin tournaments and three index assignment
Briskorn, Dirk; Drexl, Andreas; Spieksma, Frits C. R. - 2005
In general scheduling a sports league is a difficult combinatorial optimization problem. We study some variants of round robin tournaments and analyze the relationship with the planar three index assignment problem. The complexity of scheduling a round robin tournaments is settled by a reduction...

Integer programming models for round robin tournaments
Briskorn, Dirk; Drexl, Andreas - 2006
Generally speaking in sports competition a number of teams play against each other over a period of time according to a certain scheme. The round robin scheme is very popular in many team sports like soccer and basketball. In this paper we study several basic variants of round robin tournaments....

Pricing the generalized assignment problem
Drexl, Andreas; Jørnsten, Kurt - 2007
The generalized assignment problem (GAP) examines the maximum profit assignment of jobs to processors such that each job is assigned to precisely one processor subject to capacity restrictions on the processors. Due to the fact that the GAP is an NP-hard integer program dual prices are not...

A boolean satisfiability approach to the resource-constrained project scheduling problem
Horbach, Andrei - 2009
We formulate the resource-constrained project scheduling problem as a satisfiabil-ity problem and adapt a satisfiability solver for the specific domain of the problem. Our solver is lightweight and shows good performance both in finding feasible solutions and in proving lower bounds. Our...
