Constraint (S6)

[fontanf]

Constraint (S6) is not clear to me:

The number of items i packed in a stack s must not exceed the smallest "max stackability" ISMi of the items i.

Does that mean that:

• For each item i, the number of items i in a stack must not exceed ISMi
• For each item i in a given stack, the number of items in this stack must not exceed ISMi ?

Hello,

Yes, the 2 assumptions are correct. The second assumption implies the first one.

The meaning of constraint S6 is : for any stack s, the number of items in stack s cannot exceed the smallest "max stackability" ISM associated with the items of stack s.

Thanks, that's clear now
