Is the knapsack problem AP problem?

Is the knapsack problem AP problem?

One of the most stubborn questions in computer science and mathematics is whether these “NP” problems, including the knapsack problem, are truly different from “P” problems, those that can be solved in what is called polynomial time.

What exactly is the goal of knapsack problem?

What is the objective of the knapsack problem? Explanation: The objective is to fill the knapsack of some given volume with different materials such that the value of selected items is maximized.

Why is it called knapsack?

A knapsack is a bag with two straps that you wear over your shoulders, leaving your arms free. It comes from the German knappen, “to bite,” and some experts believe that the name evolved from the fact that soldiers carried food in their knapsacks.

What is the time complexity of greedy knapsack problem?

Time complexity of fractionak knapsack using greedy algorithm is O(n^2)??

What are the two types of knapsack problems?

There are different kind of knapsack problems:

• 0-1 Knapsack Problem → In this type of knapsack problem, there is only one item of each kind (or we can pick only one).
• Bounded Knapsack Problem (BKP) → In this case, the quantity of each item can exceed 1 but can’t be infinitely present i.e., there is an upper bound on it.

How to solve the problem of the knapsack problem?

In the supermarket there are n packages (n ≤ 100) the package i has weight W [i] ≤ 100 and value V [i] ≤ 100. A thief breaks into the supermarket, the thief cannot carry weight exceeding M (M ≤ 100). The problem to be solved here is: which packages the thief will take away to get the highest value? Maximum weight M and the number of packages n.

Is the knapsack problem NP hard or pseudo polynomial time?

The knapsack problem is NP-hard and appears very frequently in practical, real-life situations. A dynamic programming solution for the knapsack problem runs in pseudo-polynomial time and is arguably the easiest way to approach many of these problems on a programming contest.

Is there an upper bound to the unbounded knapsack problem?

The unbounded knapsack problem (UKP) places no upper bound on the number of copies of each kind of item and can be formulated as above except for that the only restriction on is that it is a non-negative integer.

Is there a maximum weight for a knapsack?

A maximum weight W . The amount of each type of item should be included in the knapsack to maximize profit sum without exceeding weight capacity W and subject to the bounded quantity for each item type. The Unbounded Knapsack Problem – You have an unbounded quantity of each item type, instead of a bounded quantity.
