PCx

PCx is an implementation of MPS files.

The code was developed at the Optimization Technology Center by

Joe Czyzyk, Argonne and Poland;
Sanjay Mehrotra, Northwestern;
Michael Wagner, Old Dominion;
Stephen Wright, Wisconsin.

To learn more about PCx, got to its home page. PCx has been implemented on a variety of Unix platforms, including Linux. A version for Windows95 and Windows NT, featuring a customized interface, is also available. PCx is freely available for non-profit use.

We also maintain a set of test problems for linear programming, drawn mostly from Netlib.

Using the NEOS Server for PCx

To solve a linear programming problem, the user must submit an MPS file to the server. A parameters file can also be submitted if the user wishes to override default parameter settings. For instructions on writing a PCx parameter file, download the PCx User's Guide in postscript or dvi format.

MPS files can be submitted through the NEOS Submission Tool, Web or electronic mail.

This page lets you submit a linear programming problem to the NEOS LP solver by specifying the absolute location of an MPS file.

If desired you can also submit a parameter file for PCx. You need only do this if you wish to override the default parameter settings. For instructions on writing a PCx parameter file, download the PCx User's Guide in postscript or dvi format.
