WebbDefinition 1: An output bin is named an L pack if it contains one item, and it is called an S pack if it has no L items. Definition 2: is the number of output bins in OPT solution, and ∗ is the number of output bins in the proposed algorithm. Two possible kinds of output bins ( pack and 𝑆 pack) are shown in figure 1. WebbIn order to show that problem 1 is in NP, we follow your advice and use the fact that a number is not prime iff it has a non-trivial divisor. Problems in NP have an algorithm which accepts a "proof" that the input belongs to the language. These algorithms must satisfy two properties: Every x ∈ L has some proof π. No x ∉ L has any proof π.
