Pinned topic Very slow Interactive window

‏2013-07-11T15:21:50Z |

Hallo,

 

I have one question:

I work in the interactive window in CPLEX. If the problem size is a little bit bigger (ca. 6000 variables and 3000 constraint divided in 7 classes of constraints) every time I want to see the constraints in the interactive window after the solution process CPLEX is very slow and it takes a lot of time until he is finished. Sometimes CPLEX crashes. Is there a possibility to avoid this?

Thanks and regards

    Hallo,

    as far as I know I have no .sav file.

    I think I have enough memory on my machine. Following settings are in the oplide file:

    --launcher.XXMaxPermSize
    400m
    -clean
    -vmargs
    -Xmx2000m
    -Xms2000m

     

    Regards
