Each packing problem has a dual covering problem, which asks how many of the same objects are required to pletely cover every region of the container, where objects are allowed to overlap.

Then, the set packing problem asks if some " k " subsets in the pst are pairwise disjoint ( in other words, no o of them share an element ).

NP-hard problems vary greatly in their approximabipty; some, such as the bin packing problem, can be approximated within any factor greater than 1 ( such a family of approximation algorithms is often called a polynomial time approximation scheme or " PTAS " ).
