PackLib² is a library of benchmark instances of packing problems. Unlike previous attempts like² is not only a collection of data sets. It aims at gathering information that up to now has been scattered. Besides problem instances it features references to articles defining and using these data sets, results for the benchmarks obtained by different researchers, algorithms and integer programming formulations developed by these researchers.
In short PackLib² aims at being a one stop location for researchers doing computational work in the field of orthogonal packing.
