The second property needs to be explained in detail. The most common problem being solved is the 0-1 knapsack problem, which restricts the number x i -th kind of item. Ī 1999 study of the Stony Brook University Algorithm Repository showed that, out of 75 algorithmic problems related to the field of combinatorial algorithms and algorithm engineering, the knapsack problem was the 19th most popular and the third most needed after suffix trees and the bin packing problem. Of the possible subsets of problems whose total point values add up to 100, a knapsack algorithm would determine which subset gives each student the highest possible score. The students are asked to answer all of the questions to the best of their abilities. Feuerman and Weiss proposed a system in which students are given a heterogeneous test with a total of 125 possible points. However, on tests with a heterogeneous distribution of point values, it is more difficult to provide choices. For example, if an exam contains 12 questions each worth 10 points, the test-taker need only answer 10 questions to achieve a maximum possible score of 100 points. For small examples, it is a fairly simple process to provide the test-takers with such a choice. One early application of knapsack algorithms was in the construction and scoring of tests in which the test-takers have a choice as to which questions they answer.

Knapsack problems appear in real-world decision-making processes in a wide variety of fields, such as finding the least wasteful way to cut raw materials, selection of investments and portfolios, selection of assets for asset-backed securitization, and generating keys for the Merkle–Hellman and other knapsack cryptosystems.

The knapsack problem has been studied for more than a century, with early works dating as far back as 1897. The problem often arises in resource allocation where the decision-makers have to choose from a set of non-divisible projects or tasks under a fixed budget or time constraint, respectively. 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. Given a set of items, each with a weight and a value, determine which items to include in the collection so that the total weight is less than or equal to a given limit and the total value is as large as possible. The knapsack problem is the following problem in combinatorial optimization: (Solution: if any number of each book is available, then three yellow books and three grey books if only the shown books are available, then all except for the green book.) Problem in combinatorial optimization Example of a one-dimensional (constraint) knapsack problem: which books should be chosen to maximize the amount of money while still keeping the overall weight under or equal to 15 kg? A multiple constrained problem could consider both the weight and volume of the books.
