    Hi,

    I'm trying to use cplex 12.3 populate() method to retriev solution pool, but even through cplex.getSolnPoolNreplaced() returns a positive number (72), calling cplex.getObjValue(2) results in "CPLEX Error 3024: No solution pool exists." error. What I might be forgetting?

    Kind Regards,
    Sergej

    Hi,

    I figured it out myself. I didn't notice that I was changing the problem before accessing solution pool. According, to the manual it had to reset solution pool.
