Since abs(x-y) <= 42 is not a linear function, this is not directly supported. However, you can get the same effect in PYMPROG with: -42 <= x-y <= 42 hope it helps, sorry for the late response.

try the function/method vobj().

Hi Julia, thanks for letting me know things worked out well in the end. And I will document it to help others out who might encounter similar problems, I suppose this is from really old version of pymprog. Best regards, Yingjie

Hi Julia, Sorry again for the late response, I should check it more often seriously. The usual way to modify your objective coeficients is to use parameters, you may look at this example: http://pymprog.sourceforge.net/advanced.html#assign I tried the fva.py script, but it requres options to start running. Can you give me a commandline with options so that I can replicate the problem? Regards, Yingjie

Hi Julia, Sorry for the late response, it seems that problem is caused by a bad objective...
