11.10. DOUBLE INFORMATION ITEMS 245 MSK DINF INTPNT DUAL OBJ Dual objective value reported by the interior-point optimizer. MSK DINF INTPNT FACTOR NUM FLOPS An estimate of the number of flops used in the factorization. MSK DINF INTPNT OPT STATUS This measure should converge to +1 if the problem has a primal-dual optimal solution, and converge to -1 if problem is (strictly) primal or dual infeasible. Furthermore, if the measure converges to 0 the problem is usually ill-posed. MSK DINF INTPNT ORDER TIME Order time (in seconds). MSK DINF INTPNT PRIMAL FEAS Primal feasibility measure reported by the interior-point optimizers. (For the interior-point optimizer this measure does not directly related to the original problem because a homogeneous model is employed). MSK DINF INTPNT PRIMAL OBJ Primal objective value reported by the interior-point optimizer. MSK DINF INTPNT TIME Time spent within the interior-point optimizer since its invocation. MSK DINF MIO CONSTRUCT SOLUTION OBJ If MOSEK has successfully constructed an integer feasible solution, then this item contains the optimal objective value corresponding to the feasible solution. MSK DINF MIO HEURISTIC TIME Time spent in the optimizer while solving the relaxtions. MSK DINF MIO OBJ ABS GAP Given the mixed-integer optimizer has computed a feasible solution and a bound on the optimal objective value, then this item contains the absolute gap defined by Otherwise it has the value -1.0. MSK DINF MIO OBJ BOUND |(objective value of feasible solution) − (objective bound)|. The best known bound on the objective function. This value is undefined until at least one relaxation has been solved: To see if this is the case check that MSK IINF MIO NUM RELAX is stricly positive.
