Difference between Optimal solution and Found solution in AIMMS Progress


Badge

What is the difference on the program status of “Found Solution” with Optimal solution. Does “found solution” status shows the feasible result not the optimal one? Please explain.

Hi @sarah rohaizad. You get program status 'Found solution’ if no objective has been specified for the mathematical program. In that case the solver "only” has to find a feasible solution.

I see. My problem right now, I’ve used the same input in AIMMS but each time I execute it, I will get different status. Sometimes I got “Found Solutions” and “Optimal”. I did not change any codes or touch anything. I just simply execute it.

Hi @sarah rohaizad. I do not know what is going on. Would it be possible to attach your project here, preferably after adding it to a zip file, such that we can investigate this issue? You can also send it to our support by email if your project contains sensitive information.

Alright. I have already figured out which part that I’ve missing.  Thankyou!
