Hi Jaromil  No, I am searching for Farkas Dual because the problem is infeasible, this unbdd is used to get the dual of the constraints if the problem infeasible(called "unbounded dual"): in AMPL i...

Hi Jaromil  Thanks for your help, so what  I don't understand how I can get the dual unbounded of a specific constraint for an infeasible model?? in AMPL it is simply : constraint.dunbdd but it is ...
