All Jacobian elements in the row are very small
Posted: Fri Jun 10, 2011 6:54 pm
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!

** Warning ** All Jacobian elements in the rows marked
below are
less than the absolute pivot tolerance
1.0E-10 (Rtpiva)
in the final point. Only slacks or
artificials can
be basic in these rows.
A better scaling or better bounds on the
variables
may help the optimization.
