    Hi Sirui,

    There are some parameters to control Gurobi's Behavior: Please see Parameter Guidelines.
    The log shows that finding an incumbent is one of the issue. Here are parameters that may be useful:

    • MIPFocus=1: Focus on finding a feasible solution
    • NoRelHeurTime=Appropriate seconds: Runs the no-relaxation heuristic before solving the root relaxation to find a high quality solution. 

    Also, reformulation may be helpful in improving Bounds: General modeling tips to improve a formulation

    Thanks,
    Ryuta
