Consider, then, the formal definition of an algorithm stated in Figure 5.1. 非正式的,松散定义的概念在日常生活中是可接受和常见的,但科学必须基于明确定义的术语。然后,考虑图5.1中所述算法的形式定义。 Note that the definition requires that the set of steps in an algorithm be ordered. This means ...
By an algorithm one usually means a system of computations that, for a certain class of mathematical problems, given a textdoi:10.1007/978-94-017-2973-4_6V. A. UspenskiSpringer NetherlandsV. Uspenski. To the definition of algorithms. In A. Shiryayev, editor, Selected Works of A. N....
We have come to a turning point in the study of the theory of computation. We continue to speak of Turing machines, but our real focus from now on is on algorithms. That is, the Turing machine merely serves as a precise model for the definition of algorithm. We skip over the extensive...
RSA is a type of asymmetric encryption, which uses linked public and private keys. Symmetric encryption uses only a private key. How does the RSA algorithm work? Use of the RSA algorithm typically consists of four stages: key generation, key distribution, encryption and decryption: ...
This section proves that the singularities of the ICZT on the unit circle are related to the elements of the Farey sequence of order n − 1, where n is the size of the transform. Definition 1. A Farey sequence of order n is denoted by Fn. It consists of all rational numbers in th...
The algorithm originates from"Efficient string matching: an aid to bibliographic search"(CACM, Volume 18, Issue 6, June 1975) by Alfred V. Aho and Margaret J. Corasick. See also the definition and reference implementation onnist.gov.
Before we analyze the properties of Algorithm 1, we will first introduce the following definition. Definition 4 [9] Let P,Q∈Rm×n, the matrices P,Q are called orthogonal to each other, if tr(PTQ)=0. Lemma 5 For the sequences Ri(k),Pl(k)(i=1,…,M,l=1,…,N,k=1,2,…,...

In general, analgorithmis a description of a procedure that terminates with a result. For example, thefactorialof a number x is x multiplied by x-1 multiplied by x-2 and so on until it is multiplied by 1. The factorial of 6 is 6! = 6 x 5 x 4 x 3 x 2 x 1=720. This is ...
