Why is the Knapsack problem NP complete even when it has complexity O(nW)?
Can you explain to me why the Knapsack problem is considered NP-complete despite having a complexity of O(nW)?
Sure, the Knapsack problem is considered NP-complete because it belongs to the class of problems that are difficult to solve exactly, but easy to verify the solution. The O(nW) complexity refers to the time it takes to compute the solution, but it doesn't necessarily mean the problem is easy to solve.
