Start Optimization Command

The Start command starts the optimization process for the active model. Once Evolver is running, the Progress window will open. See Evolver Progress for more information.

The Progress window displays:

• Trial - The total number of trials that have been executed, and can also indicate how many of these trials were valid (all the hard constraints were satisfied). 
• Runtime - The elapsed time in the run.
• Original - The original value in the target cell.
• Best - The best target cell value found so far.

The toolbar at the bottom of the Progress window includes the following options (from left to right):

• Display Excel Updating Options - This turns Excel Updating Options on or off.  With this option on, the screen will update every iteration.
• Display Evolver Watcher - This displays the Evolver Watcher window.
• Run - This resumes the Evolver process after it has been paused.
• Pause - This allows you to pause the Evolver process.  While it is paused, you can open and explore the Evolver Watcher and change parameters, look at the whole population, view a status report, or copy a graph. 
• Stop - This stops the optimization process.
