[Scip] Solving a MINLP in SCIP

[Apurv Shukla]

Hello
I need to solve a MINLP problem using SCIP (using Ipopt for nonlinear
part). I have implemented the model in SCIP using expression trees and
nonlinear constraint handlers. Then I call scipsolve to solve the model.
However I think that SCIP is unable to use Ipopt for solving the nonlinear
program generated at each branching node. I have checked the availability
of Ipopt to SCIP using SCIPisIpoptAvailableIpopt. For help I am using the
same procedure as in the example string (
http://scip.zib.de/doc/examples/CallableLibrary/string_8c_source.php).
How can I make sure that SCIP uses Ipopt to solve the nonlinear program
generated at each node?
