  • 1.  Docplex version of Heuristic Callback for MIP

    Posted Thu September 09, 2021 03:33 PM
    Is there a heuristic callback for the DOcplex MP module?

    Heuristic callback in regular CPLEX: https://www.ibm.com/docs/en/icos/12.8.0.0?topic=SSSA5P_12.8.0/ilog.odms.cplex.help/refpythoncplex/html/cplex.callbacks.HeuristicCallback-class.html

    Thanks,
    Louis

    You can access to all CPLEX capabilities: if they are not provided at docplex level, you can always use the CPLEX python low api.

    Examples of callbacks have been delivered in the last docplex version of last week.
    See for example, https://github.com/IBMDecisionOptimization/docplex-examples/blob/master/examples/mp/callbacks/heuristic_callback.py
