<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>1.) Does it make sense to use the options
„num_resolve_at_root“ and „num_resolve_at_note“ only
for B-BB? Or can I use it for B-OA, B-Hyb and B-QG, too? I have read in the
user’s manual of bonmin-0.1.4, you can use the option for all algorithms.
In the user’s manual of bonmin-0.99.2 it should only be reasonable for
B-BB. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>2. ) Can you explain me the sense of the option
„max_consecutive_infeasible“? If the problem of a node in the tree
is infeasible, why should I continue branching? <o:p></o:p></span></font></p>

<p class=MsoNormal style='text-autospace:none'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>3.) “ No specific heuristic
method for treating nonconvex problems is implemented yet within the OA
framework. But for the pure branch-and-bound B-BB, we implemented a few options
having in mind that lower bounds provided by Ipopt should not be trusted, and
with the goal of trying to get good solutions. Such options are at a very
experimental stage.“ (Bonmin-0.99.2 User’s Manual page 16 chapter
5.3) Which options are implemented in B-BB?<o:p></o:p></span></font></p>
