  • 1.  cplex.solve() in VB takes long time

    Hi all,

    In my VB application cplex.solve() takes 3min to solve. I use the command

    If cplex.solve() then

    ...

    End if

    When exporting the problem to a .mps-file and using cplex in cmd it only takes 4 seconds to get the solution. Why is that?

    Any help?

    If you export to a SAV file instead, do you get the same behavior with the interactive?

    Problem solved: Both methods take the same time. I used the wrong .mps-file in the interactive optimizer ;)
