Dual of a model

Dear Gams Users,
how can I find the dual of a problem which is written in Gams?
Thanks in advance for help.

Hakan,

If your question is about finding dual values of equations, you may need to append a piece of GAMS code to your main GAMS program to do the stuff for you. Something like …

*Marginal (dual) values
DISPLAY .m;

Whereas if you are asking about Lagrangian dual problem formulation, it is a different issue.

Hope this helps.

Dear Destin,
I am not asking how to find dual values and also Lagrangian dual problem formulation. For given a linear programming problem, I would like to find its dual in Gams.
