One: Prim algorithm1. OverviewPrimm algorithm (prim algorithm). An algorithm in graph theory. The smallest spanning tree can be searched in weighted connected graphs. This is the tree formed by the subset of edges that the algorithm searches for. Contains not only all the vertices in the connected graph (English: Verte
In the greedy algorithm (greedy method), the methods of constructing the optimal solution gradually are adopted. At each stage, a seemingly optimal decision is made (under certain criteria). Once a decision is made, it cannot be changed. The basis for making greedy decisions is called the greedy rule (greedy criterion).

Dixtra algorithm (Dijkstra ' s algorithm)Find the quickest path to use algorithm-the Dixtra algorithm (Dijkstra's algorithm).Using the Dixtra algorithm step(1) Find the cheapest node and get to the node within the shortest time.(2
I believe we all have the experience of finding text content under Linux, such as when we use VIM to find a word or a paragraph in a text file, Linux responds quickly and gives results, especially handy and quick!So, we have the wood to think about how Linux is correctly matched to the strings we need in voluminous text? This involves a pattern matching algorithm!1. Pattern matchingWhat is pattern matching?

The Dykstra algorithm (Dijkstra ' s algorithm) was presented by the Dutch computer scientist Eizhor Dextra. The Dicos algorithm uses breadth-first search to solve the single-source shortest path problem of nonnegative weighted graphs, and the algorit
Maximum Expectation Algorithm(Expectation-Maximization Algorithm, TranslationExpectation Maximization Algorithm) Is used for searching in statistics and depends on the Maximum Likelihood Estimation of Parameters in the probability model of unobserved recessive variables.

Introduction:
Consistent hashing algorithm a distributed hash (DHT) implementation algorithm, proposed by MIT in 1997, aims to solve the hot spot problem in the Internet, the original intention and carp very similar. Consistent hashing fixes the problem with the simple hashing algorithm used by Carp, which allows distributed hashing (DHT) to be truly applied in
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.

Before starting this article, the nagging words:
1: First, before reading this article, you should at least understand, what is the finite state machine, what is the KMP algorithm, because, this article is from the source of KMP, finite stateMachine, because, KMP is the DFA (deterministic finite automaton) on the simplification.2: Many KMP articles (limited automata
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
This LZ and you share the last two algorithms of GC, the replication algorithm and the tagging/finishing algorithm. As mentioned in the previous chapter on the marking/elimination algorithm, both of these algorithms evolve on this basis, and what are the two algorithms that optimize the previous tagging/removal algorithms?

D1,D2,D3 is a subset of samples of young, middle-aged and old age, respectively.
Age-Conditional information gain is
Information gain with work
Have information about the house gain
Information gain on credit conditions
Finally, the information gain value of each feature is compared, and the information gain value of its own house is maximal for the characteristic A3, so the feature A3 is chosen

Rplace.cTitle: Assume that the string "Qwer TYUBFG hsdf jjhg" exists, and that the string has a large enough space-writing algorithm to replace the space characters with "%20".Requirements: Time complexity: O (n), spatial complexity: S (1).Algorithm Analysis:To achieve a time complexity of O (n), a loop must be used, and the loop control is controlled by the array length n, which can be used multiple loops.
You must be able to read it. Algorithm base Book code example based on Python more than 400 diagrams, a vivid introduction to the implementation of the algorithm to show the advantages and disadvantages of the performance of different algorithms teach you to use common algorithms to solve daily problems faced by the actual programming

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
between any two points is updated to:by knowing that, when compared to only allowing transit through the number 1th vertices, this allows the transfer through vertices 1 and 2nd, making e[1][3] and e[4][3] shorter distances. in the same vein, the shortest distance between any two points is continued in cases where only 1, 2, and 3rd vertices are allowed to be brokered. The shortest distance between any two points is updated as follows:Finally, all vertices are allowed as a transit, and the fina
