Is the knapsack problem np complete

WitrynaHence, we see that Knapsack is not NP-complete if the given input is unary (assuming P 6= NP), but NP-complete when the given input is binary. Such problems are called … Witryna14 sie 2024 · The Knapsack Problem belongs to a class of problems known to mathematicians as NP-Complete, meaning that no efficient algorithmic solution has been identified. The best we can hope for is an approximate solution that will be reasonably close. Another example is The Traveling Salesman Problem.

NP-complete decision problems on deterministic automata

Witryna16 sie 2024 · The knapsack problem (1) has been extensively studied; it is an instance of an NP-complete problem, which means that unless P = N P, there is no prospect of polynomially scalable (with n) solution methods. The solution strategies for large scale knapsack problems involve relaxations, heuristics and meta-heuristics, including … Witryna16 maj 2024 · We have reformed the problem to be exactly the original knapsack problem, therefore it must be NP-complete as well. The beauty of this method is that I personally have no idea what NP complete it; I just proved that inverse knapsack and knapsack are perfectly equivalent.

Did you know?

WitrynaNo, its not known to be NP-complete, and it would be very surprising if it were. This is because its decision version is known to be in NP ∩ co-NP. (Decision version: Does n have a prime factor < k ?) It is in NP, because a factor p < k such that p ∣ n serves as a witness of a yes instance.
