set_obj_boundSet initial "at least better than" guess for objective function. void set_obj_bound(lprec *lp, REAL obj_bound); Return Value set_obj_bound has no return value. Parameters lp Pointer to previously created lp model.

RemarksThe set_obj_bound function specifies the initial "at least better than"
guess for objective function. This is only used in the branch-and-bound
algorithm when integer variables exist in the model. All solutions with a worse
objective value than this value are immediately rejected. This can result in
faster solving times, but it can be difficult to predict what value to take for
this bound. Also there is the chance that the found solution is not the most
optimal one. Example
