MathProgBenchmarks.jl

A Julia package for automatic download and parsing of linear, quadratic and integer programming instances.

Supported datasets:

• Netlib
• MIPLIB 2017
• Mittelmann LP benchmark

Getting started

1. To see which instances are available, call list_instances(dataset) with dataset in (Netlib, MIPLIB2017, MittelmannLP).
2. To read a specific instance, call read_instance(dataset, name) where name isa String.
3. The returned problem format is QPSData from QPSReader.jl.

More details are available in the docstrings.

Tips

The problem source files are downloaded automatically thanks to DataDeps.jl. Note that each download has to be validated manually from the REPL. This doesn't work well when the triggering line of code is executed with VSCode's Julia extension, better run it in the REPL directly. An alternative is to set ENV["DATADEPS_ALWAYS_ACCEPT"] = true.

The decompressed instances can be rather large (over 80 GB for the complete MIPLIB 2017 collection). If you need to clean up some space, you can delete unneeded files inside the folder located at MathProgBenchmarks.MPS_SCRATCH.
