Problem Defintion

The input is given by n items {i₁, i₂, ... i_n}. Each item comes with a non-negative value v_i and a non-negative and integral size w_i. Additionally, a non-negative integral capacity W is also given.

The output should be a subset S ⊆ {i₁, i₂, ... i_n} that maximizes the value of all objects of the subset:

 ∑vi
i∈S

so they all "fit" within the capacity:

 ∑wi ≤ W
i∈S
