Hello :slight_smile: I am using JuMP, and a solver named Hypatia. I want to change the tol_inconsistent (the tolerance to numerical imprecision) to 1e-12. I found on the web that I should use this : julia > MOI.set(model, MOI.RelativeGapTolerance(), 1e-9) I should for this use the following : …

You probably want model = Model(Hypatia.Optimizer) set_attribute(model, "tol_inconsistent", 1e-9) (I didn’t test, but this is how solver attributes should be set.) After searching the web for quite a long time, I finally ask my question here Next time, don’t wait so long :smile:

Thans a lot, it is perfect ! And I also found

MOI.set(model, MOI.RawOptimizerAttribute(“tol_inconsistent”), 1e-11)

have a nice day !
