    Hi Jan,

    It is not possible to retrieve the sub-optimal pool solutions during a callback since it is not possible to change parameters in a callback. You can only access the values for the current best solution.
    You could save objective and/or variable solution values during a MIP callback whenever a new solution is found to use this information later on.

    I hope this helps,
    Marika
