I have an optimization problem with binary variables only and the objective function has a sum that evolves index i and i+1.
All my optimization options are set to automatically, thus I would like to know how can I see what process CPLEX is using to find my solutions, this is, branch and bound? with which possible heuristics or metaheuristics. Is there a way to get a report on this?
I have a complex function and the optimization process never stops so I simply restrict the time the solver works. To identify the potential of my solution (after 400 seconds run) I need to understand the process CPLEX uses.
Thanks in advance.

if you are using the IDE, you should have a look at the engine log tab.
You can read some info in the documentation at
