    I try to solve a problem using branch and cut in the CPLEX. Since I am a newer to CPLEX。 I have several questions (maybe very simple for others).

    In order to optimize the efficiency of cpu time and optimal result, I need to revise certain cuts in order to strengthen the relaxation for my special application. Therefore I need to revise the internal function of various kinds of cuts in IloCplex.
    For example (cplex.MIRCuts), but I look for its original code in .h file, only what I find is about this cut is
    MIRCuts = CPX_PARAM_MIRCUTS, how do I revise a specific code the cplex offer in C++ concert?

    Thanks!

    The code you are asking for is CPLEX internal and the implementation details are actually a trade secret. CPLEX is not open source, so you cannot look at any algorithmic details in the source code.
