GAMS World Forum

Hello everyone,

Im not a big GAMS expert, so I'm having some difficulties trying to create a variable, i hope this isn't too trivial. I know the bounds for the default are -inf to +inf and for the integer are 0 to +inf. However, for my model I require negative integer numbers as well. So basically the bounds of the default variable but only with integers. Does anyone know how to achieve this?

Many thanks in advance!

It is as simple as setting the lower bound of an integer variable to -inf:

That did the trick, thank you Michael!
