    Hi Sina,

    You cannot get information about the branching. (Also note that the variables that Gurobi branches on may not be your variables at all since the model is transformed during presolve.)

    As for the BranchDir parameter, this determines the order in which the current node's child nodes are explored. The terms "down branch" and "up branch" refer to rounding down or up. (E.g. the down branch is the one where the branching variable is rounded down.) There is no setting for depth-first-search.
