How can I export an IIS in .lp format from mosel?
Hi! I have a model written in mosel. I know how to get the IIS when the model is infeasible but it seems I can only print the constraint and variable names from mosel. I am looking for a procedure ...
IIS will respect the normal time limit controls.
However, if it takes too long, a better option is to configure which restrictions IIS should try to test using the IISOPS control:

For example, if the binary variables can never be relaxed (which is typically the case), then setting the 0th bit of this control will limit the amount of work greatly.
