SubMIP Scale

Type : Selection

Range : The settings listed below

Default : Standard

This option decides how to scale the problem matrix when CPLEX solves a subMIP during MIP optimization. Possible values are:

  • None (no scaling)

  • Standard (use equilibration scaling)

  • Aggressive (use aggressive scaling)

SubMIPS are described in the section ‘SubMIP’ of the CPLEX 20.1 help.

Note

  • This rarely used option is helpful only in rare “corner” cases where there is clear evidence that the default scaling value is really inappropriate for this particular problem.
