Hi,
I saw a couple of threads on this topic, but I don't think they completely
answered my question. I am getting the "PROBLEM HAS NO PRIMAL FEASIBLE
SOLUTION" from glpsol. This doesn't surprise me as I am currently debugging my
input file. I have a MathProg model of my problem by my data sets are so
large, I am trying to produce a CPLEX LP format file for input instead to avoid
the long model translation step. The reason I mention this is that I know the
MathProg model is good but my Java code to generate a CPLEX LP format file must
not correspond to the MathProg model exactly yet. So this brings me to the
hope that the glpk presolver could offer more insight about which constraints
it finds unsatisfiable. Even if it told me one of them, it would be a great
clue for my debugging. If there is a way to do this through the API (vs.
glpsol), that's fine too.
Any advice appreciated. I'd be happy to provide more information if it is
helpful. Thanks in advance.
Joey
