Compressed MPS Datasets

MPSC is a dataset directory which contains files of compressed MPS datasets.

MPS files, in turn, store information in a standard format that defines various linear programming problems. MPS files are text files. They tend to be large and verbose, and so it is useful to compress them when they are not in use.
