Although DLX can improve efficiency .... But for NPC, there is no need to be too efficient, and there is only one point of test.So as long as Dfs fills in, until the spaces are all filled up, be aware of the update and recovery of global variables in DFS.As for the method of storage, just consider the non-repetition of each small block of each row in each column.#include #includeusing namespacestd;intCNT =0;//indicates the number of remaining spaces to fillstructpoint{intx, y;}; Point epts[Bayi+

Recently nothing to do, according to video Tutorial wrote a Sudoku game, very rough there are many places to modify. Let's talk about this game.1. Customize a View control to display a 9*9 grid on the screen, which is actually a horizontal drawing of 8 lines, a vertical drawing of 8 jumpers, and then a few of the lines to be bold. So that's the 9*9 lattice.2. Initialize the numbers on the game interface with a string1 String str_int = "360000000004230

A few days ago, I saw an interview book with a question about the generation of the sudoku game. So I wanted to implement it myself, read the code of others, and modified some of it myself, the core idea of the code is to use deep priority search. When the searched node meets the condition, search for the next point. Otherwise, the code will be rolled back. Program running diagram: Public void getSudoku (int [] [] array, LEVEL level) {clear (array);

Determine if a 9x9 sudoku is valid. Just follow the rules below to verify that the numbers you have filled are valid. 1-9the number can appear only once per line. Numbers 1-9 can appear only once in each column. The numbers 1-9 3x3 can only appear once in each palace separated by a thick solid line. is a partially populated, valid Sudoku.Sudoku part of the space has been filled in the number, the blank lattice with the ‘.‘ expres

After a few days of work free time to write a Sudoku game on Android, today also applied for several release platform account, released, Google Play to receive 25 knives, and this in the mainland basic access is not, so temporarily did not buy. Writing applications on the mobile platform is fun and feels like a simple application, but it's hard to write interesting apps with elegant code. I've got a new idea lately, and I've always wanted a phone app

The implementation of this algorithm is to simulate the thinking and computing process of the human brain. If you need it, you can refer to it. 1) when we get a question, we will first follow the conditions we already know, sort and analyze the data. It is equivalent to writing all "OK items" in the 9th Palace, and marking "Possible options ". Function refreshStat () 2) afterwards, the thinking will enter the cycle of speculation/verification. In cells 9, you can try "Possible options" to verif

Test instructionsGive you a 9*9 matrix that separates the two elements adjacent to the same row with a single space. Where 1-9 represents the already filled number of the position, the question mark (?) indicates the number you want to fill. The solution of this Sudoku is output and there is only one solution for each group.Ideas:Record the vacant place, each vacant place has 9 in the state, DFS + pruning processing other, with scanf input, get () tle
