NETLIB LP Test Problems

This area contains the netlib test set for linear programming. We include

• Input files for each problem ( MPS format)
• AMPL model and data files for the SCSD problems
• The underlying application
• Peculiarities of each problem: redundancies in the formulation, degeneracy, features that may cause difficulties for some solvers.
• Optimal objective values and solutions.

We don't have complete information about many of the problems. If you know something we don't know, please drop us a line.

As on the netlib repository, we partition the problems into three sets:

• The standard test set, all of which have primal-dual solutions
• The infeasible test set, for which there are of course no solutions (your super-duper code should of course diagnose infeasibility)
• The Kennington problems, which is a set of 20 or so large problems arising from Military Aircraft Applications.
