CUTEr has been superceded by CUTEst and is no longer supported. Please proceed to the new web site. The following pages are simply provided as a historical record.
[January, 2009]
Decvelopent of CUTEr migrated to the development website. Please go there for all the latest news.

[January, 2007]
Updated MEX interface to return the complete sparse Hessian instead of the lower triangle only, for consistency with the dense tools.

[September, 2005]
Added new tools pbname, varnames and connames. See man pages for details.

[July, 2005]
Added updated interface to KNITRO 4.0. Added support for the GNU gfortran Fortran 90/95 compiler. This compiler is now part of GCC 4.x and is not to be confused with g95.

[June, 2005]
Updated nearly all man pages. They now contain equations which are best viewed using
man -p e manpage
Check your local man settings.

[March, 2005]
CUTEr and SifDec are now available on MAC OS-X platforms. Thanks to Mike Friedlander!
Fixed a bug in the interface to CG+ and a problem in the interface to IPOPT in single precision. Thanks to Ling-Yun Wu.

[February, 2005]
CUTEr and SifDec now have an online discussion forum to solve user problems, submit contributions and for general discussion.

[September, 2004]
Added new interfaces to the packages CG+, CG_Descent, TRON and updated the interfaces to LBFGS and L-BFGS-B.

[May, 2004]
Added support for GNU g95 Fortran 90/95 compiler on Linux i386 machines.

[June, 2003]
Added an interface to NITSOL (Pernice and Walker). Added the flags -L, --blas and --lapack to the CUTEr scripts. See the man pages for details.

[April 7th, 2003]
CUTEr compiles out-of-the-box on Windows 2000 and Windows XP platforms running Cygwin. Make sure to have g77 and gcc installed, as well as the basic Unix tools such as grep, sed, awk and make. In the installation, pretend you are using Linux. Thanks to Hande Benson.
Note 1: Cygwin comes with the tcsh shell and no csh. You may have to create the symbolic link csh -> tcsh in /bin.
Note 2: Make sure not to unpack the CUTEr archive with WinZip, which would not properly retrieve LF and CR/LF characters. Many thanks to Brad Bell for his numerous detailed comments in this matter.
Note 3: A native version for Windows might be available in the not-too-distant future. Please let me know if you would be interested.

[March 15th, 2003]
Installation phase of CUTEr has been revamped, so no external program need be installed by the user. This helps users install CUTEr on servers not equipped with the X environment, while retaining the advantages of make. Consistent interfacing between the Fortran compilers and a selection of C/C++ compilers was implemented.

[January 15th, 2003]
CUTEr interfaces Argonne National Lab's TAO, the Toolkit for Advanced Optimization, and John Reid's LA04 from the HSL 2002, implementing a steepest-edge simplex method.

[October 7th, 2002]
New C header file cuter.h aiding in the design of interfaces between the CUTEr tools and packages written in C. Added an interface to the linesearch-based primal-dual interior-point code LOQO, authored by Robert Vanderbei. Many thanks to Andreas Wächter for some of the programming and Hande Benson for testing and comments. The whole software should be reinstalled.
Important note: The communication between C and Fortran is highly platform-dependent but also compiler-dependent. Hence, not all combinations have been tested yet. The C interface has been successfully tested under Linux with g77/gcc and ifc/gcc, and under Solaris with f77/cc, f77/gcc, f90/cc and f90/gcc. No guarantees at this time for other combinations, but all comments or information are warmly welcome!

[June 6th, 2002]
New interface to the primal-dual interior-point package IPOPT 2.0. Download the updated CUTEr distribution. The software should be re-installed because new dependencies have been added.

The Maros and Meszaros convex QP collection has been updated to remove DOS-style end-of-line characters.

This section will contain information on bug fixes, updates, patches, new releases, new platform support, etc.

Please check back regularly.
