Rodrigue, If you hold a valid license in your name or your department/company GAMS will make the version that can be used with this license available to you. Just email sales|support@gams.com your request (including the license) -Michael Thank you Michael for your reply. Your suggestion was useful....

Hi the GAMS community, I have a valid GAMS license for an old version (between 25.2 to 25.8 I think) for 64 bytes windows. I sent my request to GAMS corporation to allow me download that version. But I didn't get any answer 1 year now. The problem is that my computer was stolen. Therefore, I lose al...

Dans votre code, le fichier USAM_5.xls est importé à partir de Excel mais vous n'avez pas envoyé cela. Du coup on ne peut pas vous aider sans avoir eu cela. Aussi, il serait mieux de traduire votre message en anglais pour permettre à ceux qui n'ont pas le français comme première langue de vous aider...

Il est assez difficile de te proposer une solution efficace à ton problème tant que très peu d'indications sont données sur le modèle. Si tu ne peux pas partager ton code, il faudrait néanmoins essayer ceci: - Entre model et solve, ajoute l'option <nom_modele>.iterlim=0; - lance la résolution. Gams ...

Hi BFA,

Thank you very much for your reply. You are right. The problem were on "Bcen2" as element of the subset "af". I've missed the digit "2" while typing. It's okay now.

Cheers,

Il est possible que ce que vous appelez variables ne soient que des paramètres. Vous semblez construire un modèle EGC et apparemment cette erreur apparaît à la section des données et calibration. Si c'est le cas, ça signifie que vous avez déclaré IMO(tr), etc... Comme des paramètres et logiquement u...

Thank you bussiek.

I think the best way is to change the system to 64 bit. Can someone show me how to do that?

Hello everyone, I changed my computer and actually I use a 32-bit processor. However, I'm not able to install the actual GAMS studio. The system fails at each trial. I observed from the GAMS website that there is no any difference between the 32-bit and 64-bit files. How can I overcome this issue? R...

I saw where the problem relies on. Indeed, as a square system I was supposed to have the same number of independent equations as endogenous variables. Therefore, I observed that equations 1&4 are both the same. So there are dependent. I had to remove on of them. When suppressing the equation 1 f...
