SymmetricAlgorithmUsed in combination with asymmetric algorithms, such:
The sender has a public key and the receiver has a private key.
1. Sender:
First, the sender generates a random symmetric key, encrypts the data with the symmetric key, and puts it in a digital envelope. Then, the sender uses the public key to package the random symmetric key, put it in a digital envelope, and finally transmits the digital envelope to the receiver.

Summary: This chapter describes the examples of insertion sorting and algorithm analysis, proof of non-variant loops, combined sorting (divide and conquer), and algorithm analysis.
1. Insert sorting
Similar to the playing card insertion process, set a [1... j-1] is an array of sorted order, insert a [J] into a [1... in J-1], making a [J] an array of sorted orders, j

2,Theorem:Directed Graph G has no loop. If the directed graph G does not have a reverse edge.
3. Theorem: the topological-sort (g) algorithm can generate topological sorting for directed acyclic graph G.
5. Strongly Connected branches
1. In a directed graph, if any two different points are reachable, the directed graph is strongly connected. A strongly connected subgraph of a directed graph is calledStrongly Connected branches.

Summaryhave been interested in machine learning, has no time to study, today is just the weekend, have time to see the major technical forum, just see a good machine learning article, here to share to everyone.Machine learning is undoubtedly a hot topic in the field of current data analysis. Many people use machine learning algorithms more or less in their usual work. The IT manager network here summarizes common machine learning
Here are some general basics, but it's still very useful to actually do machine learning. As the key to the application of machine learning on current projects such as recommender systems and DSPs, I think data processing is very important because in many cases, machine learning algorithms are pre-requisites and require data.Machine learning emphasizes three key words: algorithm, experience, and performance, as shown in the process.It is shown that ma
Introduction
There are two main compression algorithms: lossy and lossless. Lossy compression algorithms reduce files by removing small details that require a large amount of data to be stored under fidelity conditions. In lossy compression, it is impossible to restore the original file because some necessary data is removed. Lossy compression is mainly used to store images and audio files. At the same time
Although programming languages should be learned, it is more important to learn computer algorithms and theories, because computer algorithms and theories are more important. Because computer languages and development platforms are changing with each passing day, the algorithms and theories remain unchanged, such as data structures,

What is an algorithm?In short, any well-defined calculation step can be called an algorithm that accepts one or a set of values as input and outputs one or a set of values. (Source: Homas H. Cormen, Chales E. Leiserson, 3rd edition of the algorithmic introduction)It can be understood that the algorithm is a series of steps to solve a particular problem (not only the computer needs the algorithm, we also use the algorithm in our daily life). The algorithm must have the following 3 important featu
