February 2003 I tested Matlab 6.5 and found a bug. Scriptfiles (e.g. OCC solution files) are read extremly slow. Mathworks confirmed this bug and suggested the following workaround: “This is indeed a bug in MATLAB 6.5 (R13) that has been forwarded to our development staff for investigation. The potential workaround: disable acceleration before executing the script and restore it after. The command to disable acceleration is: feature accel off and the command to enable it is: feature accel on This workaround reduced the execution time of the script in MATLAB 6.5 (R13) to approximately the same as the execution time in MATLAB 6.1 (R12.1).”
However, I suggest users with R13 should disable accel for the whole session, or use Matlab 6.1 in the meantime.
January 2003 Future development of OCC: I plan to further develop this package. Development has been slowed down by starting a new job and by moving back to Germany. Next steps will include: - IPOPT updating, switch to CYGWIN tools. - Documentation, step by step user guide for offline optimization - Porting OCC to Mac OS X - More demo models. - Further improvements of GUI and user-friendliness.
September 2002 - New Publication Recently a paper has been submitted to Computers and Chemical Engineering which uses the OptControlCentre for the dynamic online-optimization of the Tennessee Eastman Challenge Problem. Please use the download link below.
September 2002 - New Jacobian Check Routine August 2002 - Matlab 6.1, Maple 8 and Visual FORTRAN 6.5 tested. No incompatibilites found. OCC runs without any changes. July 2002 - Online Optimization Output overhaul, automatic report generation. All changes, further improvements and bug fixes have been added to the CVS repository. Please stay tuned, please subscribe to the newsletter.
