The nearest neighbor algorithm was one of the first algorithms used to solve the travelling salesman problem approximately. In that problem, the salesman starts at a random city and repeatedly visits the nearest city until all have been visited. The algorithm quickly yields a short tour, but usually not the optimal one.
In cryptography, ARIA is a block cipher [1] designed in 2003 by a large group of South Korean researchers. [2] In 2004, the Korean Agency for Technology and Standards selected it as a standard cryptographic technique. The algorithm uses a substitution–permutation network structure based on AES. The interface is the same as AES: 128-bit block ...
In statistics, naive Bayes classifiers are a family of linear "probabilistic classifiers" which assumes that the features are conditionally independent, given the target class. The strength (naivety) of this assumption is what gives the classifier its name. These classifiers are among the simplest Bayesian network models.
Interpolation sort. Interpolation sort is a sorting algorithm that is a kind of bucket sort. It uses an interpolation formula to assign data to the bucket. A general interpolation formula is: Interpolation = INT ( ( (Array [i] - min) / (max - min)) * (ArraySize - 1))
Prewitt operator. The Prewitt operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in the image, the result of the Prewitt operator is either the corresponding gradient ...
Substitution–permutation network. A sketch of a substitution–permutation network with 3 rounds, encrypting a plaintext block of 16 bits into a ciphertext block of 16 bits. The S-boxes are the S, the P-boxes are the same P, and the round keys are the K. In cryptography, an SP-network, or substitution–permutation network ( SPN ), is a ...
In computer graphics, the Cohen–Sutherland algorithm is an algorithm used for line clipping. The algorithm divides a two-dimensional space into 9 regions and then efficiently determines the lines and portions of lines that are visible in the central region of interest (the viewport ). The algorithm was developed in 1967 during flight ...
The first public collision was published on 23 February 2017. [2] SHA-1 is prone to length extension attacks. In cryptography, SHA-1 ( Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160- bit (20- byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits.
