Setting IntegralityFocus=1 accelerates solution?

    Sometimes even small changes in the solution path (which is the case when you change parameter settings) can have huge effects on the performance, this is called "solver variability".

    In the case of IntegralityFocus, Gurobi performs additional more detailed feasibility checks of incumbent solutions, so maybe some solutions have not been declared as feasible before because of numerical issues.
    Additionally, Gurobi does some additional branching steps that could be helpful in your case.

    Best regards,
