WebThe knapsack problem is a well-known problem in combinatorial optimization. The traditional 0–1 knapsack problem is defined by ∣ N ∣ items, where N = {1, 2, 3, …, n, …} is the set of items. Each item has an associated weight, Wn, and value, Pn.

But from my notes the Brute Force 0/1 Knapsack is O ( 2 N) with space O ( N). I think that is for the recursive solution but my brute force is not recursive, so is my complexity correct ? asymptotics computational-complexity Share Cite Follow edited Feb 13, 2024 at 9:25
Several algorithms are available to solve knapsack problems, based on the dynamic programming approach, the branch and bound approach or hybridizations of both approaches. The unbounded knapsack problem (UKP) places no restriction on the number of copies of each kind of item. Besides, here we assume that subject to and WebThe fractional knapsack problem can be solved by first sorting the items according to their values, and it can be done in O (NlogN) This approach starts with finding the most valuable item, and we consider the most valuable item as much as possible, so start with a highest value item denoted by v i.
