Dear mr/ms,

For a school project I have been working in AIMMS. However after solving our problem, we need to validate our model. Our professor said that we had to look at the #variables and the #constraints shown in the progress feed. However, after searching on internet for a few hours we could not find anything that defined these numbers. Are there some basic calculation steps to find the #constraints and the #variables?

I hope to hear from you soon.

Kind regards,

Stan Loog.

@Stan Loog , if you press CTRL+P in AIMMS, it will open a Progress Window. You can also access this in the toolbar, Windows → Progress Window. 

 

This window will contain information about the math model that you are solving. Number of constraints, variables, nonzeroes, gap, best bound, solving time, etc. 

 

You can also retrieve these numbers using math program suffices. See https://documentation.aimms.com/functionreference/suffices/mathematical-program-suffices/index.html

 

If you are solving mpMinCost then mpMinCost.NumberofConstraints will return the number of constraints in that math program.
