[Cbc] Passing bounds to CBC as parameters?

[Christoph Picker]

Hi Gabrielle,

thanks a lot for your reply! The command line interface does not accept 
"setCutoff" as a valid parameter as far as I see though.
I'd like to use CBC as a Stand-Alone solver and run it on files I 
generate through a PureBasic program.

The functions you mention are accessible from within the source code, 
correct? Is there any way to achieve a similar result through command 
line inputs?
The documentation I found on COIN OR also seems to focus much more on 
source code integration/modification.
Admittedly, I don't have a strong IT-background, so I'd like to use a 
simpler solution if possible.

Have a good day as well!

Best regards,
Christoph
