Dear GAMS friends!
Hope you are fine.
I have a GAMS code with more than 3000 constraints, as i run the model i receive an exit code of 7.
I started reducing the constraints till i 16 and that is where my model gets the feasible. But as i add one more constraints to the 16 constraints which i got the optimal solution, the exit code 7 appears.
http://interfaces.gams-software.com/doku.php?id=env:gams_return_codes
In the above link, it is written that this exit code refers to a licencing error.
So it means that the edition of the GAMS i have cannot solve the problem? Because i do not have the license?
But the question is that GAMS is a free software and can be downloaded from its web site without a need of subscription.
Do you have any idea of what is going on?
So what do you suggest me to do?
Looking forward for your response;
Cordially;
Ali

GAMS is not a free software.
GAMS Corp., in order to spread the software use, makes available a free of charge limited version, in order to run more complex models, you must pay for it.
Check model limits in the botton of the page.

Hi!!!
Try to use neos server. It is possible to you to send your model and it will solve the model for you giving back the solution. Note that your model can not have external files.
Cheers
