I would like to implement the following condition on two variables:

How much greater?
Absent a finite number, I suspect that there is no MILP representation.
If there is only one such pair of variables,
the best solution might be to represent it as two separate problems.
*) If the amount of variable a is zero, then the amount of variable b is not
restricted.
