the reason why I am creating this new thread instead of just reading the answers to this particular question that have been given before is that I feel I just don't fully understand the whole idea ...

I'm conceptualizing a solver for a variant of sudoku called multi-sudoku, where multiple boards overlap like so: If I understand the game correctly, you must solve each grid in such a way that t...

Yes, I know this is nothing new and there are many questions already out there (it even has its own tag), but I'd like to create a Sudoku Solver in Java solely for the purpose of training myself to...

Is there any algorithm that solves ANY traditional sudoku puzzle, WITHOUT guessing? Here Guessing means trying an candidate and see how far it goes, if a contradiction is found with the guess, bac...

You're given a solution to a Sudoku puzzle. Write the code to check if it's a valid solution. Your function signature should be: boolean isValid(int starti, int startj, int endi, int endj) ...

So, I've done a fair bit of reading into generation of a Sudoku puzzle. From what I can tell, the standard way to have a Sudoku puzzle of a desired difficulty is to generate a puzzle, and then grad...

I went through the manual and documentation but still don't understand. I'm trying to implement a sudoku solution where after writing out all the other rules of the game, I've added label(Board) ac...

I am trying to build a 4 x 4 sudoku solver by using the genetic algorithm. I have some issues with values converging to local minima. I am using a ranked approach and removing the bottom two ranked...

I'm struggling with a backtracking algorithm to determine wether a Sudoku has a unique solution or if it has multiple Solutions. Here's the backtracking code i use: static boolean solve(int i, in...

I'm look for the "how do you find it" because I have no idea how to approach finding the algorithm complexity of my program. I wrote a sudoku solver using java, without efficiency in mind (I wante...

Is there an algorithm or way I can get initial state sudoku puzzles for a sudoku game. Preferably with the ability to have different levels of difficulty?

How many possible unique ways are there to generate a Sudoku Puzzle?? I can think of only two possible ways 1) Take a solved Sudoku puzzle and shuffle the rows and columns 2) Generate a rand...

I'm looking to implement a very simple algorithm that uses brute-force back-tracking to solve Sudoku grids. The problem I'm facing is that in my implementation I included two instance variables for...

I made an algorithm to generate sudokus, but it was terribly inefficient. Each puzzle took minutes to generate. So now I am trying to write it again in optimal way. But I am experiencing some...

In my last question seen here: Sudoku - Region testing I asked how to check the 3x3 regions and someone was able to give me a satisfactory answer (although it involved a LOT of tinkering to get it ...

I am doing this assignment, make a program that solves sudoku. I have a panel with a grid of SudokuTextBox extends JFormattedTextField. I have a MaskFormatter so that it only accepts one integer pe...

I'm trying to code an algorithm that creates a legal Sudoku board in either Java or Javascript. Neither work, and I'm not entirely sure why. Essentially, the problem in both programs is that eithe...

I've been working on a Sudoku Solver, my current solver uses the backtracking algorithm but it still takes too long. I'm hoping to get it down to less than a second for most cases. As such, I've d...

I've a problem with my sudoku solving method. The program works like this; the board is empty when started, the users adds a couple of numbers to the board and then by hitting a Solve-button the pr...

A Sudoku puzzle is minimal (also called irreducible) if it has a unique solution, but removing any digit would yield a puzzle with multiple solutions. In other words, every digit is necessary to de...

First of all, I'll state that this is a university assignment so I'm not asking for someone to write the code for me I just need to be pointed in the right direction. :) Ok, so I need to write an ...

I've taken on the task of creating a sudoku solver using a genetic algorithm. Initialization: Store the given values in each chromosome, and then randomly generate values such that each row is a v...

I am building a Sudoku game for fun, written in Javascript. Everything works fine, board is generated completely with a single solution each time. My only problem is, and this is what's keeping me...

So I have this university assignment to solve Sudoku... I read about Algorithm X and Dancing algorithm, but they didn't help me. I need to make it with backtracking. I hard-coded some of the index...

I'm creating a sudoku generator, using a 'brute-force' randomity approach. I have been able to check the x / y axis for duplicate numbers just fine using the code: for(l=0; l<9; l++){//Makes al...
