Web18 mei 2024 · Here is what a knapsack/rucksack problem means (taken from Wikipedia):. Given a set of items, each with a weight and a value, determine the number of each item to include in a collection so that the total weight is less than or equal to a given limit and the total value is as large as possible. WebThe algorithm below does exactly that. The parameters of function knapsack are: int index = index of the item you need to decide to take or not (we start with the last element of the array and we work toward the first) int size = size still available at the backpack. int weights [] = array with the weights of all items.
