Karush-Kuhn-Tucker optimality conditions:

KKT.PE: max.abs.err = 0.00e+00 on row 0
        max.rel.err = 0.00e+00 on row 0
        High quality

KKT.PB: max.abs.err = 2.13e+00 on row 2
        max.rel.err = 7.86e-01 on row 2
        PRIMAL SOLUTION IS INFEASIBLE

KKT.DE: max.abs.err = 2.22e-16 on column 1
        max.rel.err = 5.92e-17 on column 1
        High quality

KKT.DB: max.abs.err = 0.00e+00 on row 0
        max.rel.err = 0.00e+00 on row 0
        High quality
