Knapsack Problem

Some people refer to it as the rucksack problem, but it is also known as the Knapsack algorithm. This is something applied in what is called combinatorial optimization. For instance, suppose there is a set of things with individual masses and a certain value on each, we can establish the number of every particular object to count in a group to ensure the entire weight is lower than or as required, same as a set boundary and the absolute assessment is as big as possible. The problem was given the name due to its origins and imaginations about the challenged faced by an individual constrained through a defined-size knapsack while required to fill it with items having the most value.

Its significance

It has a lot of significance as it usually comes up during resource allocation and particularly in the presence of financial challenges. It is usually studied in disciplines such as computer science, applied mathematics, combinatorics, complexity theory and cryptography. The problem has greatly been under study for over a hundred years now. The initial works on it dates back to 1897. The problem and the name are also linked with one mathematician in history known as Tobias Dantzig. However, the name is believed to have been first told in conventional tales before being applied in the computation world.


This problem was ranked as the eighteenth most common and the fourth most required problem. This was in research that used seventy five algorithmic problems conducted at Stony Brook University Algorithm Repository in 1998. Knapsack problems are normally seen in the actual-world processes of making decisions in various fields like finding the ways of slicing raw materials in a manner that is less wasteful, seating portfolios and investment contests, seating assets contest for securitization backed by assets as well as the generation of Merkle-Hellman keys together with other knapsack cryptosystems.

One of the oldest applications of these algorithms is in the development and scoring if tests where those who took the tests had a choice of answering the questions of their liking. In simple terms, it is used to as a fair procedure of offering students with such an option. It is very simple: in an exam with twelve questions with ten points each, then the taker needs to attempt ten questions in order to get a possible maximum score of a hundred points. However in a case where the questions have different points, Knapsack algorithm helps in establishing the set which gives an individual the maximum likely score.
