2DPackLib

Library of two-dimensional orthogonal cutting and packing instances.

Also called: 2DPackLib · 2D Pack Lib

A library of two-dimensional orthogonal (rectangular) cutting and packing benchmark instances and references, by Iori et al. (2022). It provides 2D bin packing, strip packing, and orthogonal knapsack instances in a standard format, making it a direct benchmark for 2D Bin Packing, 2D Strip Packing, and 2D Knapsack. For 2D Irregular Nesting, however, it is recorded only as has_adjacent_benchmark: the packing methodology is related, but it targets rectangles, not arbitrary polygons. Misclassifying it as a direct nesting benchmark would be inaccurate.

Claims & evidence

Every relationship is a claim with an evidence grade; applicable problem-to-problem relationships also carry an equivalence level. See the evidence policy.

A–X describes evidence reliability; E0–E4 describes mathematical similarity between problems. The two axes are independent.
