Hi,
I solve my GAMS model by MPEC solver and 5 infeasible
solution with the following warning.
Does anybody have any idea how to address this warning, or
what this warning means?
Thanks a lot!

Hi,
It happen the same error. I dont know how to solve the jacobian
elements.

I finally solve this problem by assigning suitable starting point of
our problem. Namely I gave propoer .lo values to some nonlinear
variables. Hope this can help other people in the future.

hallo lili
i also have the same problem like you had 2 years ago.
1 error(s): Infeasible row with only small Jacobian elements.
what did you have done to solve this problem?
thx

Recently, I use nlpec solver to solve a bi-level program with complementary constranits. I have ecountered the same problem. I find that there is no non-linear variables in my model and the bound of variables can not be set arbitrarily for some reason. Follows by the option setting below, I got the correat solution
option MPEC = nlpec;
$onecho > nlpec.opt
refType mult
slack positive
initmu 1.0
numsolves 4
updatefac 0.1
finalmu 1e-6
$offecho
Note that the initmu must not set too big.
