Problem- Insufficient Memory

Hello,

i got the Problem that my isnt solved because of the failure “insufficient memory” (conopt 3). And with other solvers i got a similar failure.

Where is the mistake? .

Hi Alexander



Your model is simply too big. You have over 7 million variables and over 2 million constraints. For a nonlinear model this is a lot.

You should check if you really need all these variables and constraints.
