A set of integers is called prime independent if none of it is a prime multiple of another. An integer a are said to be a prime multiple of b if,
A = b x k (where K is a prime [1])
So 6 is a prime multiple of 2, but 8 are not. And for example, {2, 8, the is prime independent but {2, 8,} or {3, 6} ar
Sina Weibo has changed a lot, officially opened the hand for a period of time Weibo. com domain name. This is Sina will micro-blog independent split part of the plan, but also Sina Weibo business "to Sina" an important step. But such to Sina is also very elementary and shallow, the new prodigal domain name will still coexist with the new domain name for a long time , Micro Bo also still share with Sina account system, Many features, including blog binding, are full of Sina's color , and t
1. The relationship between each other(1) Controller-to-view correlationThey are two-way relationships, but the controller is more proactive.When the controller is active, it can decide to display that view.When view is active, view determines which controller's action the data will be sent back to. When the view needs data, it determines which Controller's action the data should be taken from.(2) The relationship between view and modelView station on the more active side, model is defined as a

You only need to press the Enter key to generate a different new Sudoku!
If you are interested in developing a Sudoku game, you can randomly mask a certain number of grids. The higher the difficulty is, the more grids there are, in this way, the sudoku game must have a solution, but the solution is not necessarily unique. To ensure the uniqueness of the solution, we need to use a method similar to this to let the computer first perform the
EX1:Joey 80% sure he put the missing key in one of the two pockets of his coat. He was 40% sure to put it in the left pocket and 40% OK in the right pocket. If you check the left pocket and find that the key is not found, then what is the condition probability of the key in the right pocket?Analysis: Very basic conditional probability of the problem, the key to solve is to find out which event is the event we want to solve the condition of the event.To solve the conditional probability problem,
is controlled by pixel. In WPF, device-independent, which is controlled by WPF units.1 WPF unit = 1/96 inch. That is, on a 96DPI display, 1 WPF Unit = 1 pixel.That is, in a 120DPI environment, 1 WPF unit = 1.25 pixels. (120/96).Similar device independence can be achieved in Windows Form by modifying the AutoScaleMode property of the form, which is automatic in WPF.Formula: # pixels = (# WPF Units) * (DPI/96) The next issue will be more about WPF G
By the Konig theorem, the minimum vertex overwrite = The maximum match
It can be found that in a bipartite graph, as long as the vertices in the minimum vertices overwrite set are removed, there is no edge between the remaining vertices, that is, the remaining vertices are the largest vertices independent set.
Then you can use (maximum vertex independence set) = (n-least vertex overwrite) = (n-maximum match)
Girls and boys
In the normal development, there are always some ways we can be useful in different places, so we will encapsulate these methods. When we need to develop a function, we need to use a combination function (there is a link between multiple functions, that is, there is one or more common global variables) and this combination function needs to be called in many places. If you simply set this combination function to a global function whose common variables are set to global variables, you will find
A program that generates data independence
The following is a program to generate a Sudoku, which uses the depth-first Traversal method. When 9x9 is generated, it takes too long for my PC, while 3x3 and 6x6 can be generated correctly.
// MySIZE is the edges of the sudoku board, and the chessboard is the size of mySIZE * mySIZE int mySIZE = 9; void print (const vector

Description
A set of integers is called prime independent if none of its member is a prime multiple of another member. An integerAIs said to bePrime multipleOfBIf,
A = B x k(WhereKIs a prime [1])
So,6Is a prime multiple2,8Is not. And for example,{2, 8, 17}Is prime independent{2,
We've been working on a similar piece of software with Momo recently. Because the database has not been keeping up with the situation, so have to add cache. But there is a doubt here.
For a general app, what everyone sees is the same, so it's good to put that data directly into the cache. But for example, Mo mo. People nearby are not the same people that everyone sees nearby. Each person sees different data

How to add each other to the stranger on the first kind of friends: by adding friends near.
1 Install and open the MO, enter the "Nearby" interface, click on the upper left corner of "near" to filter "confirmation." (pictured below)
2 Select the need to add friends such as "Small Treasure", click "Attention" can be. (pictured below)

So far, we have seen the graph model as a data structure that can encode probability distributions.We can represent a probability distribution of a high-dimensional feature space in the form of factor decomposition.We can also think of a probability map as an independent set of columns, and a distribution must satisfy these independence.This view is more profound (you can take a look at my 5th blog, "Probability map Model 4: Bayesian network") 1
