Busy work, no way to take the time to concentrate on the "Go Language programming", with more understanding, more and more experience the small examples of this book delicate.By mastering these small examples, you can complete the full mastery of the Go FoundationRecently took time to focus on these examples. But there are some problems, and in design, it may be harder for me to understand a big algorithm. Special about the two chapter in the end of t

I. OverviewThe decision tree is an important task for the knowledge information contained in the data, so the decision tree can use unfamiliar data collection, and extract a series of rules, when these machines based on data creation rules, is the machine learning process.Second, the structure of decision treeDecision Tree:Advantages: The computational complexity is not high, the output result is easy to understand, the missing unscented sense of the median value , can process the irrelevant cha

Opengl implements line scanning algorithm and area filling algorithm, and opengl AlgorithmOverview 1. Use the line scanning algorithm to draw a line segment. A straight line consists of discrete points. 2. Use the area Filling Algorithm to draw a polygon area. The area consists of discrete points. Development Environme

Learn the reason for this algorithm: Yesterday afternoon stroll, met the girlfriend is looking at the algorithm, suddenly asked me will not Freud algorithm. I agreed to, and then spent half an hour to learn the algorithm, and 5 minutes to listen to her, and also to share with you in need of friends, so that you in the

Second, scan line algorithm (Scan-line Filling) The scan line algorithm is suitable for the area filling of the vector graphics, only need to the geometric position of the polygon area, no need to specify the seed point, suitable for the computer automatic graphics processing occasions use, such as computer games and three-dimensional CAD software rendering and so on. To fill the vector polygon region, th

1.3 Scanning line seed filling algorithm The advantages of the two seed filling algorithms described in sections 1.1 and 1.2 are very simple, with the disadvantage of using recursive algorithms, which not only require a lot of stack space to store adjacent points, but are inefficient. In order to reduce the recursive call in the algorithm and save the use of stack space, many improved algorithms are propos

The two most famous character string search algorithms are KMP algorithm (knuth-Morris-Pratt) and BM algorithm (Boyer-Moore). In the worst case, both algorithms have linear search time. However, in practice, the KMP algorithm is not much faster than the simplest C-database function strstr (), while the BM algorithm is

Process Scheduling Algorithm Linux Process Scheduling Algorithm and scheduling algorithm linux Process This section describes the process scheduling algorithm of the operating system. There are three types of Operating System Scheduling: 1. Remote Scheduling(Create a new process); 2. Middle-end scheduling(Part of the

Algorithm ---- binary search algorithm, algorithm ---- binary Binary Search is a frequently used algorithm in Ordered arrays. When you are not in contact with the binary search algorithm, the most common method is to traverse the array, compare with each element. The time is

Example of string matching algorithm implemented by PHP [Sunday algorithm], algorithm Sunday This example describes the string matching algorithm-Sunday algorithm implemented by PHP. We will share this with you for your reference. The details are as follows: The Sunday

Improved scanning-line filling algorithm The principle and implementation of the scan line filling algorithm is simple, but the requirement for storage space is high because it maintains both the active side table (AET) and the New Edge table (NET). Part of the two tables is duplicated, and the "New Edge table" is in many cases a sparse table, if you can improve it, avoid two tables, you can save storage s

First, give a non-direction graph Using the Dijkstra algorithm (Dijkstra algorithm) to find the single source shortest path with a starting point is as follows The process of calculating the shortest path from source vertex 1 to other vertices using the Dijkstra algorithm is listed in the following table. Iterative process of the Dijkstra

When it comes to string matching algorithms, it is estimated that everyone immediately thought of the KMP algorithm, who let KMP so classic, all kinds of arithmetic textbooks must have KMP ah. But the KMP algorithm is too complex for next to crash into cry. There is no simpler and more efficient algorithm than KMP, no, some, this is the Sunday

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). Example 1-4 [for change] a child buys less than 1 dollars of sugar and gives 1 dollars to a salesperson. The salesman hopes to find
