Hi,
I am solving a minimization mixed integer programming problem with branch and cut of CPLEX.
I have a IloMIPIncumbentCallback and at each new incumbent found I show the value and the time cplex found it. I would like to show also the lower bound and the of this solution. How can i do it in cplex c++?

Thanks a lot.

Use the functions that are provided by the IncumbentCallback class. For example getBestObjValue() which gives the current dual bound. Please refer to the reference documentation for further details.
