Dear Atharv, thanks a lot. This is what I was looking for. In the example transport7.py UpdateAction.Upper was used to fix the value of the variable x (in combination with the fact that variable x is positive). Is there a specific reason to use UpdateAction.Upper instead of UpdateAction.Fixed? And i...

Hello everybody,

I would like to know how I can fix some variables in a model from the Python API. For example in transport4.py (as included in GAMS). Can anybody provide some example code?

Best regards,
Viktor

I can't run your model, but the probabilities should be stored in s_rep. If not please specify the error and provide a minimal example.

See also the farmsp.gms example in the EMP example library. There the probabilities are displayed.

Hi Lutz,

I've compiled the latest GAMS Studio (1.1.0) on Ubuntu 20.04 which fixed the problem. I'm able to select text again using the keyboard.

Any chance that this issue will be fixed in the original AppImage binaries?

Best regards,

Hi Lutz,

thank you for your suggestion.

Seems to be not the most convenient option. I'll test it next week after having upgraded to Ubuntu 20.04.

Hello everyone,

If I keep shift pressed I can't move the cursor and hence can't select text. I'm using GAMS Studio 0.14.6. I've checked some older studio versions and the problems seems to start with 0.11.3 (0.11.2 still works).

I'm using Ubuntu 18.04 and GAMS 30.3.

Best regards,
Viktor
