Dear all,
I've a problem that is almost infeasible, its a large one, but the KKT
conditions that glpsol gives me is:
"KKT.PE: max.abs.err = 1.48e-12 on row 1
max.rel.err = 1.17e-16 on row 10
High quality
KKT.PB: max.abs.err = 6.01e-07 on column 1052
max.rel.err = 6.01e-07 on column 1052
Medium quality
KKT.DE: max.abs.err = 2.84e-14 on column 80
max.rel.err = 1.09e-16 on column 1168
High quality
KKT.DB: max.abs.err = 0.00e+00 on row 0
max.rel.err = 0.00e+00 on row 0
High quality"
The column that KKT.PB refers to is described thus:
1052 R_lipid B -6.0112e-07 0 1000
My glpk code fixes this column, using GLP_FX, to have the lower and
upper bounds of 0 and 1000, as you can see, but I don't understand why
the output tells me that it is trying to go below zero. I tried to
change tolbnd so that it would allow this, but it doesn't change the
result. Can anyone help me by pointing out to me what the next thing
I should try and do?
Thanks
Sam
