  • 1.  Get the variable CPLEX choose to branch using generic callback

    Posted 10/11/21 02:41 AM
    Hi folks,

    I'm using CPLEX C API. But it is not clear to me how to get the variables that CPLEX is going to branch on using a branch callback. 
    It looks like the generic callback CPXXcallbackmakebranch is only able to create a user-branch instead of accessing the default branching decision by cplex.
    Any suggestions on how to get this information with generic callback?

    Thanks in advance!

    It is indeed only possible to create a branch.  The callback is not intended to allow you to check what CPLEX would choose to do.
