    Hi Ghafour,

    I guess you are referring to the concurrent optimizer set by the Method parameter. When having only 1 core, depending on some structural data of the problem, Gurobi will either run the primal or dual simplex. Gurobi prefers the simplex algorithms over Barrier when only a few cores are available because the simplex algorithms don't benefit from multiple cores, meaning that 1 core is enough for a simplex algorithm. If you have any guess that for your specific problem, the primal, dual, or the Barrier algorithm is best, then it is recommended to set it explicitly via the Method parameter.

    Best regards,
    Jaromił
