  • 1.  Setting a memory limit?

    Hello,

    I was wondering if there was a way to set a general memory limit for the process (root + search) in CP Optimizer. Looking for something similar to CPLEX's tree memory limit parameters.

    Thanks,

    Kyle

    Hello Kyle,
    There are several parameters on IloCP used to limit the search tree : FailLimit, ChoicePointLimit, BranchLimit, SolutionLimit, FailureDirectedSearchMaxMemory ...
    see parameters doc.
    Regards,
    Chris.

    Thanks Chris.

    I saw those parameters previously, but was looking for something at a higher level that would have the solve terminated once it consumed a pre-specified amount of memory. Each of the parameters you have mentioned would have me restrict the search in an undesired way.

    Ideally something like this would be available: https://www.ibm.com/support/knowledgecenter/SSSA5P_12.6.0/ilog.odms.cplex.help/CPLEX/Parameters/topics/TreLim.html

    We don't have any other parameter about the memory usage, sorry.
