Nagel AlgorithmIn TCP/IP, no matter how much data is sent, always add a protocol header before the data. At the same time, the other party receives the data and also needs to send an ACK to confirm. To make full use of network bandwidth, TCP always wants to send big data as much as possible. (MSS parameters are set for a connection. Therefore, TCP/IP needs to be able to send data

conventions and specifications provided in this document. It also provides a "provider" architecture for implementing multiple, interoperable passwords.The Java Password extension (JCE) extends the JCA API, including APIs for encryption, key exchange, and information authentication codes (MACS). The JCE and JDK passwords together provide a platform-independent, complete password API. The JCE as an extension of the JDK will be released independently to comply with U.S. export control constraints

Dijkstra algorithm1. Definition OverviewThe Dijkstra (Dijkstra) algorithm is a typical single-source shortest path algorithm that calculates the shortest path of a node to all other nodes. The main feature is to extend from the center of the starting point to the outer layer until it expands to the end point. Dijkstra algorithm is a very representative shortest p

[Preface]This article briefly introduces the concepts related to encryption technology, and finally summarizes the existing encryption technology in java as well as its usage and examples. [Simple encryption] 1. Simple concept Plaintext: the information before encryption Ciphertext: Confidential Information Algorithms: encryption or decryption algorithms Key: The key used by the algorithm (read as miyao, correct should be miyue, but everyone reads m

Previously did not pay attention to the sorting algorithm, because there are very few application scenarios, the recent interview process found that the sorting algorithm is often asked, sometimes in some written or interview topics need to use the sorting algorithm to solve the problem, if each of their own handwritten sort, then it is quite time-consuming, And

Maximum Subsequence and algorithm analysis, and subsequence algorithm analysis. Maximum sub-sequence and algorithm analysis, sub-sequence algorithm analysis problem description: Given n integer sequences {a1, a2 ,..., an}, evaluate the function f (I, j) max {0, ak} (k: continuous from I to j). The problem is to find th

Decision tree algorithm and Decision Algorithm English name: demo-tree Decision tree is a typical classification method. It processes data first, generates readable rules and decision trees using an induction algorithm, and then analyzes new data using a decision. In essence, a decision tree is a process of classifying data through a series of rules. Decision tre

In the summary of the principle of FP tree algorithm and the principle of prefixspan algorithm, we summarize the principle of two kinds of association algorithms, FP Tree and Prefixspan, and introduce how to use these two algorithms from the practical point of view. Since there is no class library associated with the algorithm in Scikit-learn, and Spark Mllib has

Through the introduction of the previous section, learned the common pattern matching algorithm, the general idea is: The pattern string from the first character of the main string to match, each match failed, the main string record matching progress of the pointer I have to i-j+1 the fallback operation (this process is called "pointer backtracking"), while the pattern string to move backward one character position. Loop again and again until the matc

Garbage collection algorithmIn general, the garbage collection algorithm is divided into four categories:Tag-Purge algorithm The most basic algorithm is the tag-purge algorithm (mark-sweep). The algorithm is divided into "mark" and "clear" two stages: first mark the

requested by the JVM, which defaults to 1/4 of physical memory but less than 1G By default, when the free heap memory is less than 40%, the JVM increases the size specified by heap to-XMX, which can be specified by-xx:minheapfreeration=, and when the free heap memory is greater than 70%, the JVM reduces the size of the heap to the size specified by the-XMS. You can specify this column by xx:maxheapfreeration=, and for running the system, to avoid frequent resizing of heap at run time, the-XMS i

The Dijkstra algorithm of Single-source Shortest path and the Floyd algorithm of the shortest path between any two points are discussed, and today we look at two other common algorithms for finding the shortest path of single source: Bellman-ford algorithm and SPFA algorithm. As for why we put these two together, the c
