In the film animation production process, Max is an essential tool, today we will be through a dance ribbon production process to appreciate the powerful features of Max, first to preview the animation effect.
1, create a ribbon dancing path. Before making ribbons and dancing the title animation, we first want to sketch the animation effect that we want to achieve, that is, the path of ribbon

Section 14th: Snowflak
When I first came into contact with Dancing Links, I visited the csdn forum and found that someone was studying the sudoku program. I went in and looked at it because I had developed the sudoku game, some people found that using Dancing Links to solve Sudoku was the fastest, so I decided to learn about Dancing Links.

Analysis on the trojan evolution Report of "Dancing moth"I. Overview
Recently, the 360 mobile security team detected that a cloud Control Trojan was exploding. The trojan family was first captured by February 2015 mobile security teams in 360, and more than 12 thousand samples have been collected. Since the trojan has evolved from multiple versions and multiple malicious files are downloaded for malicious behavior, we name the trojan as a "Moth ".

Finally, we made a dance links ..
First, let's talk about dancing links, which is probably a magic method to deal with a wide range of coverage issues.
This algorithm processes a model called exact coverage, which means to give you a 01 matrix and requires you to select several rows so that each column has only one
Different from other searches, dancing links searches for the row to be overwritten by each c

Say, there was N items to try with one by one, when N[i] was picked, all rest n[i + 1, N-1] items would being tested one by E, too. What's more, due to recursive calls, there is a lot intermediate caching necessary to contain intermediate states. Very blindly procedure correct?Traditional backtracing i

Question: 11198-dancing digits
Each group of data has eight numbers, which may be positive or negative. It is required that the eight numbers be sorted in ascending order of the absolute values of the numbers. The sorting rule is to let a number a invite another number B to dance, so that a can be inserted to the left or right of B, and a can invite B to dance, then a * B
Solution: At first I thought about DFS, but later I found that this decision

A rectangle of N * m is given. The coordinates are (0, 0 )~ (N, m ). Then we will give you a small P rectangle with the coordinates (x1, Y1 )~ (X2, Y2), you can select the smallest rectangle so that these rectangles can overwrite the entire rectangle without overlap. (N, m
Idea: precise coverage of dancing links.
We divide the N * m rectangle into N * m small squares, so we only need to ensure that each small square is overwritten and only once.

Idea: This question is quite good. Originally, the template was not customized by myself. After understanding the Dancing Links, I found a template, and then I got a better understanding of this question, you also know how to create a matrix in practice.
Regard the matrix of n * m as n * m lattice, and act as n * m columns, just like the single number. Each rectangle has a row.
After
Analysis:DLX repeated coverage of the ingenious use, the principle of repeated coverage is exactly in line with the screening method, that is, select a number, the number of multiples or approximate can be guaranteed in the subsequent search will not be selected so modify the heuristic function, solve the largest repeat coverage. In fact, not necessarily not be selected, just choose later, either reach the goal, or achieve the goal, or not choose better than the following example 32 3 6 The answ
Dancing Links are generally used to solve the precise coverage problem. What is the precise coverage problem? This is the following:
Precise coverage of DancingLinks
Description
For the following 01 matrix, select several rows so that each column of the Matrix has only one
Lines 1, 4, and 5 are exactly covered. For details about how to use the Dancing Link to obtain this solution, refer to the code.

Question :.... Do I still use Sudoku?
First of all, the general solutions are brute-force searches .. So I learned the X Algorithm for Data Structure Optimization of dancing-links, or the DLX Algorithm for short.
Although the name of dancing-links is nice, it is actually a two-way cross linked list .. However, due to the various failures during debugging, the pointer is still looking at and worried (people
