Problems recovering MipGap
回答済みHello,
I need to test how the MIPGap evolves as I increase the execution time limit in Gurobi (self.model.setParam("TimeLimit", tl)). However, when I try to retrieve this attribute (self.model.getAttr("MIPGap")), I get the following error:
AttributeError: Unable to retrieve attribute 'MIPGap'
What could be causing this?
Thank you in advance and best regards.
NOTE: self.model.IsMIP = True and self.model.SolCount > 0

Hi Jose,
The issue is that MIPGap is not available for multiobjective models.
Multiple Objectives → other details
We haven’t attempted to generalize the notions of dual solutions or simplex bases for continuous multi-objective models, so you can’t query attributes such as Pi, RC, VBasis, or CBasis for multi-objective solutions. Because of this, we’ve concluded that the most consistent result to return for attribute IsMIP is 1. Note, however, that several MIP-specific attributes, such as ObjBound, ObjBoundC and MIPGap, are also not available. However, MIP gap and best bound can be queried for each objective using callbacks, see the respective Callback Codes.
If you're after the MIPGap for the last objective pass then you can use the
MULTIOBJ_MIPGAPcode (as in the Callback Codes section linked above).- Riley
