Hello everyone,
While solving a MINLP program using SBB- CONOPT, non-linear variable is exceeding the maximum limit i.e 1E+10. This limit can be increased by using option file conopt.opt and setting rtmaxv at higher value.I am unable to use option in the source file.if anyone can help in this regard, it will be very helpful for me.

There are two steps:
You have to tell SBB to use an option file in the usual way with “.optfile=1;†before the solve.
You have to create an option file (sbb.opt) where you tell which NLP solvers you want for the root and the sub-models and that you want the NLP solver to use an option file. This is done with sbb.opt:
Rootsolver conopt.1
Subsolver conopt.1
Where “.1†is similar to “optfile=1â€.
Good luck
