||Release of version 1.1:
||Includes hooks to incorporate alternative linear equations solvers, including WSSMP
||Computational results added for WSSMP and Ng-Peyton versions
||PCx 1.1 for Windows released
||2 minor memory bugs fixed, new linux version built
||PCx 1.1 for Windows - parameter file bug fixed
||Added DOS version 1.1, unified parameter.c for DOS, Unix, all-C versions
||AMPL interface and PCxGUI (Java interface) released.
||Unix and C versions changed to accept problems with zero rows in the constraint
matrix, and to improve efficiency of initial matrix ordering routines. (We are
working on improvements to the dense column handling, which will be released shortly.)
||Bug fix in PCx Unix and C versions. Bug affected instances with bound
constraints in whch Gondzio correctors were used.
||Fixed readmps.c to avoid core dumping on incorrect MPS input files.
||A few fixes in line search heuristic and MPS file handling; affects only a few cases.
||Fixed handling of "MI" in the BOUNDS section of MPS files; affects only
cases in which MI variables have upper bounds other than 0.
||Updated PCx-AMPL interface to fix some bugs in the interface, and
document the installation process more thoroughly. Also created
precompiled executables for Intel Solaris, Sun Solaris, and Linux.
||Fixed bug in preprocessor for bounded variables in a singleton row.
||Fixed another bug in preprocessor, again concerning row singletons.
||Updated PCx-C (C version) to use latest version of fortran-to-C utility
||Fixed minor bugs concerning handling of upper bounds (in PCx.c) and
scaling (in scale.c). Unified the unix and Matlab-ready distributions.
||Fixed hash.c to allow more than 1.3 million rows and columns; redefined
allowable hash table sizes.
||Fixed bug in memory allocation for array min_phi in PCx.c
