Set the gap for Gurobi.Optimizer in Julia-JuMP

I am trying to understand how to set the gap for Gurobi.Optimizer, because it solves too long when the default gap threshold is used (10e-4). I couldn't find it anywhere (they might be referred to as attributes or parameters).

PS: Also, I am trying to find the right tutorial or instructions on how to use the solver in JuMP. I checked here https://juliahub.com/docs/Gurobi/do9v6/0.7.7, but they don't reveal the meanings of different attributes and inputs. Please, send me one in case somebody knows.

Best, A.

You can set the MIP gap via the MIPGap parameter:

using JuMP, Gurobi

model = Model(Gurobi.Optimizer)
set_optimizer_attribute(model, "MIPGap", 0.1)

You can read more about JuMP here: https://github.com/jump-dev/Gurobi.jl
