Recursive Algorithms for data structures and algorithms C ++ and PHP, and data structures and algorithms RecursionRecursive Algorithm: it is an algorithm that calls itself directly or indirectly. Implementation process: You can use a function or sub-process to complete recursive operations by directly or indirectly calling the code in a function or sub-process. (

Eight sort algorithms that must be known [java Implementation] (3) Merge sort algorithms and Heap Sort Algorithms
I. Merge Sorting Algorithm
Basic Idea:
The Merge Sorting method combines two (or more) ordered tables into a new ordered table, that is, the sequence to be sorted is divided into several subsequences, each of which is ordered. Then combine the ordered

convergence thresholds until convergence. The HITS algorithm can also be extended to other similar sorting systems.
Hits variants
Most of the problems encountered by the HITS algorithm are because hits is a purely link-based Analysis Algorithm without considering the text content. after kleberger proposed the HITS algorithm, many researchers improved hits and proposed many variant hits algorithms, mainly including:
Improvement on hits by Monika R. he

: in all spanning trees of a connected network, the cost of all edges and the smallest spanning tree, called the minimum spanning tree.
Here are two 1.Kruskal algorithms for minimum spanning tree algorithm
This algorithm can be called "Edge method", the initial minimum spanning tree edge number is 0, each iteration selects a minimum cost edge that satisfies the condition, and joins the Edge collection of the smallest spanning tree.1. All the edges of

Preface to the book "algorithms-principles hidden behind data structures"
In the winter of 2014 AD, a biography of the legendary life of Alan Turing, the father of computer science, was released in the United States. This film is "Imitation Game". In the

I. Basic concepts of greedy Algorithms
When a problem has the optimal sub-Structural quality, we will think of using dynamic programming to solve it. But sometimes there are simpler and more effective algorithms. Let's look at an example of coin search. Assume there are four types of coins with

Examples of greedy algorithms implemented by PHP and php Algorithms
This article describes the greedy algorithm implemented by PHP. We will share this with you for your reference. The details are as follows:
Background:Greedy algorithms and data structure knowledge base algorithms can be said to be the closest

From the martial arts perspective, algorithms are the internal power of computers. learning algorithms can make a program run efficiently. At the same time, algorithms are independent from computers. No matter how technology develops, some algorithms will still exist. This is also the first condition for survival in th

Summary of some common JavaScrip algorithms: javascrip Algorithms
The following describes some common javascript algorithms. If you need them, you can refer to them. Of course, these algorithms are not only applicable to javascript, but also to other languages.

Chapter 2 asymmetric encryption algorithms-DH and asymmetric encryption algorithms-dh
Note: In this section, refer to "advanced encryption algorithms-asymmetric encryption algorithms" in Chapter 2nd of Java encryption and decryption art (version 8th"
11.1 asymmetric encryption algo

Two common cryptographic algorithms in cryptography are symmetric cryptography (single-key cryptography) and asymmetric cryptography (public key cryptography ).
The so-called symmetric key algorithm means that if the encryption key of an encryption algorithm is the same as that of the decryption key, or although it is different, it can be easily pushed to another one, that is, the key is shared by both parties.
Asymmetric Key

Chapter 1 Functions of algorithms in computing
I think the title of Chapter 1 is incorrect or inaccurate. It should be more accurate to "the role of algorithms in computers.
Chapter 1 describes the purpose and importance of algorithms. I will summarize it as follows:
1. Solve the problem.
Many problems can be solved manually with our own intuitive feelings. H

Data structures and algorithms, data structure AlgorithmsWhat is a data structure?
The data structure is divided into data and structure. Numbers, characters, graphics, and sounds are all data. The structure is divided into logical structure and storage structure. The logical structure is the abstract relationship between data. The storage structure is the storage of data in computer memory (memory, disk. Data structure studies how data is stored in c

8. Graphic explanations of sorting algorithms and text of sorting algorithms
Sorting algorithms can be divided into internal sorting and external sorting. Internal sorting means that data records are sorted in the memory, while external sorting means that the sorting data is large and cannot accommodate all sorting records at a time, you need to access external s
