Thanks!

Also: Would this affect the optimality of the returned result? I.e., do I need to set NumericFocus or Presolve for Gurobi to give me the right answer, here?

Thank you. I can confirm that the gap of 16% was also reported through the API; in the case of JuMP, when using MOI.get(model, MOI.RelativeGap()), though this should access the Gurobi library direc...

While I'd like to know what's going on, my primary concern is whether the result is, indeed, optimal; I assume there is no reason to suspect otherwise, given that Gurobi explicitly says so?

I have not added any callbacks on purpose, at least; I'm accessing Gurob i through JuMP.jl, and I guess some callbacks may have been set up there. The solver use is part of code that runs many mode...

Yes, I set the TimeLimit parameter, but it is set to 300, and this MIP finishes in 0.02 seconds. (I also set NodefileStart to 1.0.) Here is the entire log: Gurobi 9.1.1 (mac64) logging started Wed ...
