kandi X-RAY | SudokuSolver Summary

SudokuSolver is a C# library typically used in Artificial Intelligence, Machine Learning, OpenCV, Example Codes applications. SudokuSolver has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A program that works out the solution to a Sudoku puzzle by using human techniques and proofs. Because it logs the human techniques it uses, you can learn how to get past obstacles you found yourself in. It is designed with speed in mind, but there are still many improvements to be had. I'm currently just trying to write each technique before optimizing further.

You can't do const board = new SudokuSolver(board) because the board variable isn't defined yet. You need to do const board = new SudokuSolver(boardString).

Following a tutorial that is teaching how to build a sudoku solver. Created two files, SudokuMap.cs which is the data folder and SudokuMapper.cs that contained in the Workers folder. SudokuMapper.cs is suppose to map the row and column within the 9 by 9 grid.

It's just a typo. Your Find method is written to return SudokuMapper, not SudokuMap.

When you add a name to a library that means it is an private or internal library of your package. It seems that cabal currently has a bug which causes that confusing error message asking you to add SudokuSolver to your build-depends of your executable, you could instead add SudokuSolver:sud.

However, it is much more common too keep the library unnamed (or give it the same name as the package), which makes it the main public library. Then the name of the library is the same as the name of the package so you should really add SudokuSolver to the build-depends of your executable. This was the only possible option for a long time, internal libraries are relatively new. That is probably also why there are still a few issues like this.

I also notice that you can add sud as Willem van Onsem says, but only if you use cabal-version: 3.0 or earlier. With cabal-version: 3.4 you have to use the SudokuSolver:sud (package-name:internal-library-name) notation.

Edit: I have opened an issue on the cabal GitHub repo.

I have a routine in the main.cpp where user will specify which mode to execute in the program. Once the mode is specified, the corresponding block will be executed - first downcast the parent solver to the child solver and call the associated solve method in the child class.

QUESTION

Recursive sudoku algorithm works but returns incorrectly

Asked 2021-Mar-08 at 14:36

Sorry for the code dump below...!

This algorithm does sovle the sudoku puzzle (as the log in solve if empty == -1 func) but the actual output once all of the recursion unwinds is either returning the original puzzle string or returning the default case of {error: 'Puzzle cannot be solved'}.

I think it's probably a final iteration error but I've refactored and reorganised till I'm blue in the face and can't work out why it's not returning the successful output as it unwinds.

Any help would be hugely appreciated.

ANSWER

Answered 2021-Mar-08 at 14:36

The reason is that your code ignores the solution that is potentially returned from the recursive call, and instead just returns the incomplete puzzle it was initially called with:

QUESTION

Gui to visualize recursive backtracking sudoku

Asked 2020-Nov-21 at 21:52

I wrote a class a while ago to solve a sudoku game using recursive backtracking - that's working as expected.

Now I want to visualize this algorithm step by step. I basically want to see where the algorithm put which number and when it is backtracking.

I wrote all the necessary function and implemented a basic gui that already calls and displays my sudokuSolver inside my gui (after you start it and press a random key once you want to begin the solving).

Now my problem is that I want to see each step of the algorithm - see more in the SudokuSolver.solve() function.

At the moment I somehow only update my gui once the whole backtracking is finished, although my SudokuSlver.setGui() function is called during the backtracking.

Which is also the reason why my approach to "slow down" the algorithm with "Thread.sleep()" and "TimeUnit" failed.

Python class returning old value of attribute

Asked 2020-Jul-12 at 06:10

I have a main class, a second class that handles getting a sudoku grid (2D array), and a third class that solves the puzzle and is supposed to return a completed puzzle. When I run the program, the solve method works fine and prints out the solved puzzle. However, when I call SudokuSolver.get_grid() from another class, the original, unsolved grid that was passed into SudokuSolver is being returned. Also, when I tried to return self.grid from the solve() method, it always returns [[None]].

Here is my solver class:

Answered 2020-Jul-12 at 05:00

Since python passes lists by reference, you are passing a reference to the old solver's grid. You need to initialize your solver with a copy of the other grid like this:
