01 Knapsack Problem defined and explained. In this tutorial we explain why a greedy rule does not work and present a dynamic programming algorithm that fills out a table. The running time complexity of the dynamic programming algorithm is pseudo-polynomial, not quadratic, even though the table is two dimensional. Understanding the running time complexity gives a sense of why this problem is hard and why it's called "weakly NP-complete".

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. It derives its name from the problem faced by someone who is constrained by a fixed-size knapsack and must fill it with the most valuable items.

This is a common problem that is given during coding interviews in engineering firms such as Google and Microsoft.
