I have to add a constraint so that the number of types for every bin is
limited to maximum 2.
Each bin can contain a number of the same type of items (i.e. A) or max 2
different types (i.e. A and C).
it is not regarding the number of items, of course, I can have multiple
items.
If you want the types to have names, they will have to be a set.
You could just give them indices.
You will need a 2D boolean array indexed by item and type.
Once you have that, the rest should be obvious.
