Question

Difference between Optimal solution and Found solution in AIMMS Progress

S

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!
