    Hi everybody,

    I am dealing with a very badly symmetric mip model for which I have a
    separation algorithm that can separate the alternate solutions.

    Once a feasible solution is found by solver, then I am able to find
    the other ones.
    Now the question is: is there any possibility to add these cuts (which
    are changing the original model) dynamically in the course of solution
    process within ILOG Concert? or perhaps does anyone know any other
    alternative solver.

    any other suggestion and guideline?

    Many thanks in advance.
