Hello,

I have a Integer Program with 5 objective functions. For the fifth obj. function I want to set a time limit. The limit should be the maximum runtime of the other four runtimes. Thus, my question is how to get the runtime of a single objective function before optimizing it? The time limit will then be set with getMultiobjEnv and setParam.

Thanks in advance.

  Hi Daniel,

  It is possible with the use of the cbStopOneMultiObj() function. However, it requires some bookkeeping of the runtimes of the previous objectives. The example in the documentation of the cbStopOneMultiObj() function already shows an example on which you can build up.

  Best regards,
