A Tree Search Algorithm for Solving theContainer Loading Problem

Fanslau, Tobias; Bortfeldt, Andreas - Fernuniversität <Hagen> / Lehrstuhl für … - 2008

The paper presents a tree search algorithm for the three-dimensional container loading problem(3D-CLP). The 3D-CLP is the problem of loading a subset of a given set of rectangularboxes into a rectangular container so that the packed volume is maximized. The method hastwo variants: the packing...

Eine Heuristik für das mehrdimensionaleBin Packing Problem

Mack, Daniel; Bortfeldt, Andreas - Fernuniversität <Hagen> / Lehrstuhl für … - 2008

The more-dimensional bin packing problem (BPP) considered here requires packing a set ofrectangular shaped items into a minimum number of identical rectangular shaped bins. All itemsmay be rotated and the guillotine constraint has to be respected. A straightforward heuristic ispresented that is...

The Edge-Set Encoding Revisited: On the Bias of a DirectRepresentation for Trees

Tzoppe, Carsten; Rothlauf, Franz; Pesch, Hans-Josef - Betriebswirtschaftliches Institut <Mannheim>; … - 2004

variants of the edge-set encoding:the edge-set encoding without heuristics, and the edge-set encoding withheuristics. An … investigation into the bias of the edge-set encoding showsthat the crossover operator of the edge-set encoding without heuristics … isunbiased, that means it does not favor particular types of trees. In contrast,the crossover operator with heuristics is biased …
