  • 1.  Long Run time due to Memory??

    Hi-

    I have three models that are being run for 20 different values for a parameter and over 20 iterations. When I run each parameter value individually it takes about 5 seconds to solve and when I run it for 5 different parameter values it takes about 2 minutes. Needless to say when I increase it to 20 it takes a very very longtime.

    I have a feeling this is due to memory usage as that is the only explanation I can think of. To deal with this I have used .end() after each iteration for each of the Models and there corresponding data structure, but this has not helped at all.

    Any ideas??

    Thanks in advance.

    when doing multi model, you must end the objects such as IloOplModel after use.
    You can try using the new mainEndEnabled settings to better deal with the memory.
    Note that by default, end methods are not active in the IDE.
