How I used algorithms to solve the knapsack problem for my

The knapsack problem, though NP-Hard, is one of a collection of algorithms that can still be approximated to any specified degree. This means that the problem has a polynomial time approximation scheme. To be exact, the knapsack problem has a fully polynomial time approximation scheme (FPTAS). … See more 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 … 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 asset-backed securitization, … See more The knapsack problem is interesting from the perspective of computer science for many reasons: • The decision problem form of the knapsack problem (Can a value of at least V be achieved without exceeding the weight W?) is 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 number of some problem parameter such as the number of items, number of … 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 Several algorithms are available to solve knapsack problems, based on the dynamic programming approach, the branch and bound approach or hybridizations of both approaches.

WebMar 15, 2024 · We can keep doing this exchange until O P T is literally the same knapsack as P, recall P is the knapsack that ALG (greedy algorithm) produces. Therefore, we have proved by contradiction there cannot be a strictly more optimal knapsack than the knapsack produced by ALG, so P is optimal and ALG produces the optimal knapsack. . … WebKnapsack Problem .
