Q: Is there any equation attribute, that gives back the feasibility status of an equation?
What I want to do is to relax some bounds, if am equation was infeasible. I tried with equation.m, but marginals may exist, even if the equation is not highlighted with “infes”.
With recent versions of GAMS, we compute the constraint record EQU.infeas
from EQU.
l and EQU.lo/up
. This feature is used in the model feasopt1
in the GAMS model library.
