    Hi Alex,

    When a big MIP model is very difficult to be solved in OPL, could I choose a specific algorithm to solve MIP models instead of the default algorithm? and so how to set up a specific algorithm?

    Thank you,

    Nguyen

    Hi,

    you could write your own decomposition, use another algorithm and hybrid CPLEX and that algorithm ...

    You could also make your model simpler by aggregating some values and then warm start into the initial model.

    regards

    Hi Alex,

    Could you any model OPL related to the decomposition, use another algorithm and hybrid CPLEX?

     

    Thank you,

    Could you tell me know, how to set up a specific algorithm instead of the default algorithm to solve MIP models?
