I am building my first optimization model, it is quite large and also a non-linear problem. I have had my model solving on the NEOS Optimization Server and after 8 hours of trying to solve, the server cut out because it reached a time limit. So what I am wondering is if it's abnormal for models to run over 8 hours or if this is a fairly normal occurrence.
I am using the NEOS server because it is free and the solver I am using (KNITRO) is quite expensive.
Edit: I will be updating this problem later today.
