Netlib LP Data to MPS

This repository contains Netlib LP problem data that has been converted into the readily usable MPS format.

Disclaimer

The data here are the compressed MPS files and the data that need to be generated by generators from https://www.netlib.org/lp/data/, expanded into a readily usable MPS format. Please visit the original site first and check its contents carefully.

Contents

The repository includes the following:

1. Converted MPS Files: These are files that have been converted from the original LP format into MPS format for easier use.

2. Unconverted Problem Names: Some problems from the Netlib LP dataset could not be converted. The names of these problems are listed here. If you can successfully convert these, please let us know.

Unconverted Problems

The following problem sets could not be converted to MPS:

• QAP8
• QAP12
• QAP15
• STOCFOR3 For QAP8, QAP12, and QAP15, generators will need to be acquired from https://www.netlib.org/lp/generators/qap/.

For STOCFOR3, attempts to convert it resulted in the following error:

% ./std2mps
Process TIME file:
   1    TIME          STOCHFOR
  10    ENDATA
Process CORE file:

XXX -  FATAL  - Illegal record in CORE file
STD2MPS: execution terminated.

Any assistance in converting these would be greatly appreciated.
