Problem with EMP stackleberg

Hi everyone reading this,

I’m trying reformulate a perfectly competitive equilibrium model (PComp.gms) to a perfectly competitive Stackelberg model (Bilevel.gms). However when I try to run Bilevel.gms I get the following error,

\


*** JAMS VIFunc cannot be performed on model with specified direction and objective


*** JAMS Pre processing failed


I get the same error when trying to run hark-stack.gms.
Does anyone know what might be happening?

Thanks,

Corey.


PComp.gms (771 Bytes)
Bilevel.gms (953 Bytes)

Corey,

Can you send the .gms source you used for the hark-stack run, and the .lst file and .log files you get? I can run hark-stack from EMPLIB with my 24.4.6 GAMS system with no problems.

Ahh thanks.

The issue was with the GAMS version I was using. Both models work now and now Bilevel.gms does what I expected.

Thanks,

Corey.

That error would come up for both models (my model bilevel.gms and the EMP library model hark.stack.gms) when I used GAMS version 24.1. They both solved without error when I used version 24.4.6 like Steven said they should.

Corey,
You mean your origninal gams models right? What version you use for them which no problem?
