PackLib² hosts most of the orthogonal benchmark instances that have been proposed in the literature. The instances are kept in different XML-Files on a per article basis. A detailed description of the XML file format can be found here.

For easy access we provide you with different ways to browse through the XML files. On the bottom of this page you find the list of instances that are part of PackLib². By clicking on the XML symbol you can directly access the XML file. The INFO and ARTICLE box take you to different views on the XML files. The information page gives information about the creator and users of the instances. The article page shows details about the instances. Where applicable clicking on the ORLib button results in an ORLib-like file format for packing problems.

Alternatively you can also browse the instances by problem type.
