get_obj_boundReturns initial "at least better than" guess for objective function. REAL get_obj_bound(lprec *lp); Return Value get_obj_bound returns the initial "at least better than" guess for
objective function. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_lp_file, read_LP, read_mps, read_MPS RemarksThe get_obj_bound function returns 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
