The knapsack problem is the following problem in combinatorial optimization: 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. It derives its name … See more 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 See more The most common problem being solved is the 0-1 knapsack problem, which restricts the number $${\displaystyle x_{i}}$$ of copies of each kind of item to zero or one. Given a set of $${\displaystyle n}$$ items numbered from 1 up to $${\displaystyle n}$$, … See more There are many variations of the knapsack problem that have arisen from the vast number of applications of the basic problem. The main variations occur by changing the … See more 1. ^ Mathews, G. B. (25 June 1897). "On the partition of numbers" (PDF).

Each item has an associated weight (an integer) and an associated value (another integer). The problem consists of filling the knapsack without exceeding its capacity, while maximizing the overall value of its contents.
