Hello,

Is it possible to use CPLEX's MIPEmphasis parameter in docplex?

I am talking specifically about this parameter: https://www.ibm.com/docs/en/icos/12.10.0?topic=optimizer-emphasizing-feasibility-optimality

If yes, would it be possible to know how to use it? I couldn't find it in the docplex mp documentation.

Thank you,
David

Hello

You can set any CPLEX parameter from Docplex. the property `Model.parameters` returns a hierarchical parameter structure, from whoch you can get and set values,
just as with the CPLEX Python API.

In your case:

mdl.parameters.emphasis.mip = 2 # any value from 0 to 5

or

mdl.parameters.mip.tolerances.mipgap = 0.02

to set the MIP gap limit.

Hope this helps

    Philippe.
