The planar region filling algorithm is an important algorithm in the field of computer graphics, where the region fill gives the boundary of a region (or it can be without boundary, but gives the specified color), and requires that all pixel elements within the boundary range be modified to the specified color (or pattern fill). The most commonly used in area filling is the polygon fill, in this paper we di

In statistical calculations, the maximal expectation (EM) algorithm is the algorithm for finding the maximum likelihood or maximum posteriori estimation of a parameter in the probability (probabilistic) model, where the probabilistic model relies on the invisible hidden variable (latent Variable).
Maximum expectations are often used in the field of data clustering for machine learning and computer v
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

Learning to this point, found a lot of learned but long useless knowledge, over time, slowly forgotten. When the day is needed, but found to have forgotten almost, even if the document (Word, etc.), still have to learn from the beginning. Study the first semester, found that a lot of things can be learned from the blog, there are a lot of bloggers have worked hard to organize a lot of useful Bowen. So, I take this opportunity, also slowly began to organize some blog posts
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
SummaryClustering is unsupervised learning ( unsupervised learning does not rely on pre-defined classes or training instances with class tags), it classifies similar objects into the same cluster, it is observational learning, rather than example-based learning, which is somewhat like a fully automated classification. To put it bluntly, clustering (clustering) can be understood literally--the process of clustering identical, similar, close, and related object instances into one class. The common
The simplest code implementation of the fastest sorting and searching algorithm
by http://blog.csdn.net/shendl/ Preface
The core problem of the algorithm is sorting and searching. These 2 fields are the most widely used and are the most thoroughly studied. In this article I will explain the most efficient two algorithms for sorting and searching: A fast sort algorithm
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
(A book "Programmer's Practical Algorithm" (Andrew Binstock/john Rex), the Internet has a Chinese electronic version, but recommended to buy a genuine, this is a classic book. )
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 enc
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
Today began to study the Redis source code some of the tools in the implementation of the tool class in any language, the implementation of the algorithm principle should be the same, so you can take this opportunity to learn some of the more classical algorithms. Like I see today. CRC cyclic redundancy check algorithm and rand random number generation algorithm.
Introduction of genetic algorithm1.1 Overview of genetic algorithmsGenetic algorithm (genetic algorithm, short GA) is a kind of randomized search method derived from the evolutionary law of the organism (survival of the fittest, the fittest genetic mechanism), which was first proposed by Professor J.holland of the United States in 1975. Genetic algorithm is a com
Coincidentally, almost all of the popular hash map uses the DJB hash function, commonly known as "TIMES33" algorithm.
Perl, Berkeley DB, Apache, MFC, STL, and so on.
Times33 's algorithm is also very simple, is constantly multiply by 33. Nhash = nhash*33 + *key++;
I didn't find any theory to illustrate the rationality of this algorithm, it is said that only

later chapter, we will give an algorithm to convert the regular expression into a form that the machine can read, which is the poor state automaton described in this chapter.
A poor state automaton is the name that sounds scary, but in reality the motivation is not as complicated as it might seem. This concept of state machines is widely used in a wide variety of fields. The Unified Modeling Language (UML) of software engineering has a state diagram

A previous Wireless sensor network course (WSN) assigned a Dijkstra algorithm to any language in any environment. I thought, good ah, had been shouting no time to worry about the algorithm, this can be used as a breakthrough point
There are also contacts for the program paging algorithm. In general, there are two kinds of paging algorithms, one is the traditional ADO paging, the other is the select top paging algorithm. For small data tables, such as ten thousand or twenty thousand of the amount of data table, I tend to use the ADO algorithm, for large data tables, you must adopt the latte
