I am using SCIP to solve an MINLP.
Since I do not have a full licence for SCIP with GAMS, I am exporting the model in OSIL format and input it in the SCIP system provided by Zuse.
My model contains constraints smax(x1,x2,x3,...) => a
When solving a small instance using the demo GAMS/SCIP I don't encounter any problems.
When trying to input the problem into the stand alone SCIP application by using OSIL, SCIP complains that the OSIL file should not contain MAX/MIN expressions.
Is there a way to avoid this problem?
