We have to define a constraint T = Max(0, c - u) which returns 0 if c-u<=0
or the value of |c-u| if c>u.
We can't compile when we use this constraint: s.t. ret{k in K}: T[k] =
Max(0, c[k] - u[k]).

How should we define this constraint, as Gusek doesn't allow us to use a Max
function in a constraint?

Thank you!!!
