Pallet Loading

Place the maximum number of identical boxes on a pallet.

Also called: Pallet Loading · 팔레트 로딩 · Manufacturer's pallet loading

Definition

Place identical rectangular boxes, without overlap, on a pallet to maximize the count (manufacturer's pallet loading). That all boxes are identical is the key difference from general bin packing.

Example

Suppose a pallet 5×35\times3 (15 cells) and a box 2×12\times1 (90° rotation allowed). Laying every box horizontally fills a width-4 block with 6 boxes and leaves a width-1 column. Standing one box vertically in that last column yields a 7th — a mixed layout beats a single orientation (one cell empty). The combination of identical boxes and allowed rotation is what characterizes this problem.
