Comment (by compiler):

 Thanks for your reply. Yet your reply to my second question is not very
 clear to me.


 >The "milp_solver" option refers to the solution of MIPs within Bonmin
 (e.g., MIP relaxations in the B-OA algorithm), not to how Bonmin's branch-
 and-bound tree is managed (when using B-BB, B-Hyb, B-QG).

 That would imply that Bonmin is using Cplex as "LP solver" not "MILP"
 solver. First, I thought CLP was the LP solver. Second, I assumed when I
 compiled it with Cplex, it would actually use Cplex as tree manager. So
 did you mean Cplex is replacing CLP but not CBC? To be clear, I am
 interested in outer approximation algorithm, so I want the tree to be
 managed by cplex and not cbc. Is that possible?

 I am going to include bonmin results in a refereed journal article and I
 want to make sure that it does what I am expecting it to do. Is there any
 way to make bonmin report that? Some kind of log or a query or a file in
 some location?

 Thanks a lot for your time, I appreciate it.
