Strip-Packing-Probleme stellen mehrdimensionale Packprobleme dar, die sich im dreidimensionalen Fall wie folgt formulieren lassen. Eine gegebene Menge quaderförmiger Packstücke (Kisten) ist vollständig in einem quaderförmigen und in Längsrichtung offenen Container anzuordnen. Die...

The paper presents a tabu search algorithm (TSA) for the Timetabling problem at German primary schools (GPS-TTP). The GPS-TTP represents a special variant of School Time-tabling with a specific mix of constraints. At first the GPS-TTP is modelled as a binary optimization problem. The model is...

This paper presents a parallel tabu search algorithm for the container loading problem with a single container to be loaded. The emphasis is on the case of a weakly heterogeneous load. The distributed-parallel approach is based on the concept of multi-search threads according to Toulouse et al....

This paper describes the parallelization of a two-phase metaheuristic for the vehicle routing problem with time windows and a central depot (VRPTW). The underlying objective function combines the minimization of the number of vehicles in the first search phase of the metaheuristic and the...

The vehicle routing problem with time windows (VRPTW) is an extension of the well-known vehicle routing problem with a central depot. The objective function of the VRPTW considered here combines the minimization of the number of vehicles (primary criterion) and the total travel distance...

The paper presents two metaheuristics, a tabu search algorithm (TSA) and a genetic algorithm (GA), for the so-called strip packing problem. Strip packing problems represent a special class of multidimensional packing problems. In the three-dimensional case the strip packing prob-lem may be...
