Detailed Log information when we use multi-objective in Docplex

  • 1.  Detailed Log information when we use multi-objective in Docplex

    When we solve a single objective problem in Docplex, we will get the detailed log as attached in the image below. Could I please know how to get a similar log when we solve multi-objective problems? Appreciate the help.

    You need to set the CPLEX parameter multiobjective.display to value 2, instead of the default value 1.
    https://www.ibm.com/docs/en/icos/20.1.0?topic=parameters-level-display-during-multiobjective-optimization

    Here's an example:

    model = Model()
model.context.cplex_parameters.multiobjective.display = 2
...
