[SCIP] Problem in using of SCIP

[Stefan Vigerske]

Hi,

the function itself (a polynomial) looks like SCIP should be able to 
handle this. The nl.instr looks like something that is particular to the 
OPTI-toolbox interface to SCIP. Please check with them whether they can 
help you with this.

Best,
Stefan
