In large data high concurrent access, there is often a service or interface in the face of the explosion of the request is not available, or even triggered a chain reaction caused the entire system crashes. At this point you need to use one of the technical means to limit the flow, when the request reached a certain number of concurrent or rate, it is waiting, queuing, demotion, denial of service and so on. In the current limit, the two common algorithms are leaky bucket and token bucket

1. Overview The sorting algorithm is the most basic algorithm in the computer technology, and many complex algorithms use the sort. Although all sorts of sorting algorithms have been encapsulated into library functions for programmers to use, it is important to understand the idea and principle of sorting algorithm for writing high quality software.

The general minimum spanning tree algorithm is divided into two kinds of algorithms:One is the Kruskal algorithm: the idea of this algorithm is to use the idea of greed, the weight of each side of the first order, and then each time to select the current minimum edge, to determine whether this side of the point has been selected, that is already in the tree, is g

1.3 scanning line Seed FillingAlgorithm The two seed filling algorithms described in sections 1.1 and 1.2 have the advantage of being very simple. The disadvantage is that recursive algorithms are used, which not only requires a large amount of stack space to store adjacent points, and the efficiency is not high. In order to reduce recursive calls in algorithms and reduce stack space usage, many improved algorithms are proposed, one of which is the scanning line Seed Filling

One, knapsack problem description:There are n items and a backpack with a weight of M, the weight of the article I is w[i], the value is p[i]. The solution of which items are loaded into the backpack allows the sum of the costs of these items to be no more than the backpack weight and the maximum value.Second, the solution:1, greedy algorithm: Greedy algorithm based on the idea is that every choice is the b

A * algorithm is a heuristic search algorithm. People who understand BFS, DFS, or Dijkstra algorithms should know that. These algorithms are a way of blindly searching around. Heuristic Search: Heuristic search is the search in the state space to evaluate the location of each search, get the best location, and then from this location to search until the target. This can omit a lot of fearless search path,

Pattern matching algorithm for strings The locating operation of a substring is often called a pattern match of a string, where T is called a pattern string . General positioning function for substring position (Brute force)That's what I write Java code for.int Index(String s,string T,int POS) {char[] S_arr = S.tochararray (); char[] T_arr = T.tochararray ();intI,j,k;//iIs the pointer to the main string s, and J is the pointer to the pat

Chapter of Basic Statement This poster of algorithms are based on the book and the lecture of algorithms on Coursera which are taught by Robert Sedgewi CK and Kevin Wayne, writers of the book mentioned above. Chapter of "algorithm" is the fundamental of Java programming language and a brief introduction to Algorithms and DA TA structure, including their concepts. Some interesting problems and the basic implementations of them. Introduction Why We s

Dijkstra algorithm Also known as Dijkstra algorithm, is a classical shortest path algorithm, the main feature is to expand from the starting point to the outer layer, until the extension to the end point, the use of breadth-first search to solve the problem of the single source shortest path of the weighted direction graph, the
