![You and Alice and Bob are considering variants of the Pokemon problem. In the opti-
mization problem we are looking for the minimum set of packs, and there are multiple
ways to convert it to a decision problem (you probably used the standard method of
adding a threshold variable k above).
Alice considers the question "Is there a collection of packs of size 5 (or less) that includes
one of every card in the set?".
Bob considers the question "Is there a collection of packs of size [2] (or less) that
includes one of every card in the set?".
Are Alice and Bob's versions of the problem NP-complete? Either way, justify your answer
with a proof.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa0c2266a-9a17-4b5f-a3a4-de1bbbae4b7e%2F63a233f9-f925-47b9-b37c-f674d3d203c4%2Fio2ru9_processed.jpeg&w=3840&q=75)
