For example, we have two items having weights 2kg and 3kg, respectively. If we pick the 2kg item then we cannot pick 1kg item from the 2kg item (item is not divisible); we have to pick the 2kg item completely. This is a 0/1 knapsack problem in which either we pick the item completely or we will pick that item.

Where we can apply the knapsack problem in real time examples?
The knapsack problems have a variety of real life applications including financial modeling, production and inventory management systems, stratified sampling, design of queuing network models in manufacturing, and control of traffic overload in telecommunication systems.
What is the solution to the knapsack problem?
The optimal solution for the knapsack problem is always a dynamic programming solution. The interviewer can use this question to test your dynamic programming skills and see if you work for an optimized solution. Another popular solution to the knapsack problem uses recursion.
What are the two types of knapsack problem?
If there is more than one constraint (for example, both a volume limit and a weight limit, where the volume and weight of each item are not related), we get the multiple-constrained knapsack problem, multidimensional knapsack problem, or m-dimensional knapsack problem.
How many types are there in knapsack problem?
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). So, we are available with only two options for each item, either pick it (1) or leave it (0) i.e., xi∈0,1 x i ∈ 0 , 1 .
What is the use of knapsack problem?
The knapsack problem is an optimization problem used to illustrate both problem and solution. It derives its name from a scenario where one is constrained in the number of items that can be placed inside a fixed-size knapsack.
What is meant by knapsack problem?
The knapsack problem is a problem in combinatorial optimization: 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.
How knapsack problem is solved by greedy method explain?
The basic idea of the greedy approach is to calculate the ratio value/weight for each item and sort the item on basis of this ratio. Then take the item with the highest ratio and add them until we can't add the next item as a whole and at the end add the next item as much as we can.
Why is knapsack problem NP complete?
The knapsack problem is NP-complete because the known NP-complete problem subset-sum is polynomially reducible to the knapsack problem, hence every problem in [math]N\! P[/math] is reducible to the knapsack problem.
Why is a knapsack called a 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 are constraints of knapsack problem?
We first present an integer formulation for this knapsack problem, so couple constraints related with load balance, vertical (cargo) stability and fragility of the items also called load bearing.
Why is it called 0 1 knapsack problem?
In 0-1 Knapsack, items cannot be broken which means the thief should take the item as a whole or should leave it. This is reason behind calling it as 0-1 Knapsack.
What is knapsack problem Quora?
Answered 6 years ago. I'm not an expert, but here's my take: The knapsack problem is to determine the choice/placement of objects of varying sizes and values into a fixed-size knapsack/bin such that value is maximized.
What is binary knapsack problem?
Binary knapsack problem is defined as, “Given a set of items having some weight and value/profit associated with it. The knapsack problem is to find the set of items such that the total weight is less than or equal to a given limit (size of knapsack) and the total value/profit earned is as large as possible.”
