WebMay 10, 2015 · For fractional knapsack, this is very easy to show: we take any element of X, say b. If w a >= w' b (where w a is the weight of a, and w' b is the weight b has in the solution X ), we can replace b with as large a fraction of a as possible. Because a is the item with the largest value-density (this is our greedy choice), this will not make the ... WebMay 20, 2024 · Select the first ratio, which is the maximum package. The knapsack’s size can hold that package (remain > weight). Each time a package is placed in the knapsack, the size of the knapsack is reduced. Note: The 0/1 knapsack problem is a subset of the knapsack problem in that the knapsack is not filled with fractional elements.
