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...

Given a set of rectangular pieces and a rectangular container, the two-dimensional knapsackproblem (2D-KP) consists of orthogonally packing a subset of the pieces within the container suchthat the sum of the values of the packed pieces is maximized. If the value of a piece is given by itsarea...

In the container relocation problem (CRP) n items are given that belong to G different itemgroups (g = 1,…,G). The items are piled up in up to S stacks with a maximum stack height H.A move can either shift one item from the top of a stack to the top of another one (relocation)or pick an item...

The article presents a tree search algorithm (TRSA) for the strip packing problem in two and threedimensions with guillotine cutting constraint. In the 3D‐SPP we are given a set of rectangular items(boxes) and a container with fixed width and height but variable length. We have to determine...

For several decades research on intelligent techniques for decision-making has represented a particular challenge, originally taken up using modest hardware equipment, which we today would consider to be extremely weak. From earliest times onwards research which was concerned with the theory and...
