2DPackLib: a two-dimensional cutting and packing library. Two-dimensional cutting and packing problems model a large number of relevant industrial applications. The literature on practical algorithms for such problems is very large. We introduce the 2DPackLib, a library on two-dimensional orthogonal cutting and packing problems. The library makes available, in a unified format, 25 benchmarks from the literature for a total of over 3000 instances, provides direct links to surveys and typologies, and includes a list of relevant links.
