I call this the "Grocery Store" variant because I like to think of it as being like Supermarket Sweep where participants race to fill a shopping cart with the highest valued items possible.
Since the grocery store has lots of stock available, it's fine to pick the same item multiple times. Let function to ensure we select the subproblem parameters that yield the highest value.

A multiple constrained problem could consider both the weight and volume of the boxes.

(Solution: if any number of each box is available, then three yellow boxes and three grey boxes; if only the shown boxes are available, then all but the green box.) The knapsack problem or rucksack 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.Here the maximum of the empty set is taken to be zero. However, since this runtime is pseudopolynomial, this makes the (decision version of the) knapsack problem a weakly NP-complete problem.A similar dynamic programming solution for the 0/1 knapsack problem also runs in pseudo-polynomial time. From Definition A, we can know that there is no need for computing all the weights when the number of items and the items themselves that we chose are fixed.One theme in research literature is to identify what the "hard" instances of the knapsack problem look like, The goal in finding these "hard" instances is for their use in public key cryptography systems, such as the Merkle-Hellman knapsack cryptosystem.Several algorithms are available to solve knapsack problems, based on dynamic programming approach, items and the related maximum value previously, we just compare them to each other and get the maximum value ultimately and we are done.At it's most basic, Dynamic Programming is an algorithm design technique that involves identifying subproblems within the overall problem and solving them starting with the smallest one.Results of smaller subproblems are memoized, or stored for later use by the subsequent larger subproblems.Our base case is K(0) yielding a value of 0 because no item has a weight ≤ 0.For this problem we should be able to use a simple 1-dimensional table (array) from in length.In this post, we'll explain two variations of the knapsack problem: Before we dive in, though, let's first talk briefly about what Dynamic Programming entails.You may have heard the term "dynamic programming" come up during interview prep or be familiar with it from an algorithms class you took in the past.
