Hello, community.
I would like your help to know how to declare an unrestricted variable. I currently use this:

idh = [(d, p) for d in days for p in periods]
O= model.continuous_var_dict(idh,name="O",lb=-1000)

but I would like something like this:

-inf <= O <= inf

That is, not to give a specific value to lb

#DecisionOptimization

O= model.continuous_var_dict(idh,name="O",lb=-model.infinity)

should do the trick.
In CPLEX, the infinity is 1e+20. Default constructors of variables in CPLEX have a lower bound of 0.
