Some of you may have arrived at this site by clicking on a Google ad. This is an experiment that’s possible thanks to the free Google credits provided by our GoDaddy hosting plan. On our first day we’ve had 5 click-thru’s, all for a total cost of nz$1.20 a day!
OpenSolver has now moved from wordpress.com over to our GoDaddy hosted site. It took a while (longer than I’d expected, and with too many GoDaddy hiccups), but it is now up and running. Enjoy. Andrew
Better checking of parameters; better handling of Escape during long CBC runs (no DoEvents now, and a new dialog). Fixed bug in the “Last open model in CBC” where OpenSolver was waiting for CBC to close (but still allowing events to be handled, including sheet edits etc.)
Updated OpenSolver. Added a fix for sheet names with spaces, and for the definition of parameters. Added new commands to (1) Solve LP relaxation, and (2) to open CBC command line. Also added improved support for cancelling long CBC runs. A new .zip file has been uploaded. Enjoy. Andrew
