A few days ago LP play Sudoku, play to master a variety of abused, I looked to say, minutes to help you do it out,The result is of course not done.So the internet search the next Sudoku code, read the next C code, mostly recursion and the like (such as http://blog.sina.com.cn/s/blog_9e16dc4d01013s1y.html)So think, can

In this paper, we describe the method of Python's implementation of Sudoku algorithm. Share to everyone for your reference.

A piece of code of the sudoku game forgot to use a search algorithm with the depth-first or breadth-first, and used some probability algorithms for improvement. In this case, I was afraid that I would accidentally delete it in a few years, g. JS seems to be included in another blog post, so I will not post it here.At the beginning, this code had some reasons. The

Select the display after the password (b) Functional Introduction 1. After clicking on a circle, add a small circle in the center of the circle.2. The page slide appears with a following line.3. When you slide to another circle, a straight line

Only 30 lines of Python code are used to demonstrate the X algorithm and 30 lines of python If you are interested in the sudoku solution, you may have heard of the exact coverage problem. Given the collection Y of the complete set X and the subset Y of X, there is a subset Y * of Y, which makes Y * a split of X. Here i

I recently searched online for solutions to related programs when I took my children to study Sudoku and my career. I would like to share with you my hope to help you learn python.
