Remarks PCx is an interior-point predictor-corrector linear programming package. PCx is available in Fortran or C source or a variety of Windows and Unix executables, with an optional Java-based GUI interface.
A comparison between PCx and some other IP package for LP is given in Hans Mittelmann ( benchmark:
PCx uses the sparse Cholesky linear algebra routines of Esmond Ng and Barry Peyton who are in the Algorithms Group of the Mathematical Sciences Division at Oak Ridge National Laboratory.
