The algorithm treats the puzzles as minimization problems where the aim is to minimize the number of empty cells, and uses tabu search for the minimization.

Sudoku is a puzzle that has gained much popularity since its first release in a US Newspaper in 2004. The object of the original Sudoku is to fill in a partially-completed 9x9 grid with numbers 1-9 such that each row, column, and the nine 3x3 sub-grids contain no duplicate numbers.

Sep 13, 2014 · Here is my failed attempt to solve Sudoku using Simulated Annealing. ( I think it is good to fail - it makes me learn :-) ) Input to the algorithm - initial Sudoku board configuration - set of 81 numbers - where a missing number in the board is indicated by -1. For people who don't know what is constraint programming, please read this first. The programming constraint is a fast and good way for solving complex problems, but it comes with some difficulties. I was compelled to look into a Sudoku Solver in Java using the principles I have learned in a course, namely I wanted to make something that included backtracking and forward checking. Has anybody else managed to produce a Sudoku solver that uses the forward checking algorithm that is more efficient than the backtracking on its own? Sep 14, 2019 · Constraint Satisfaction Problems in Artificial Intelligence with tutorial and examples on HTML, CSS, JavaScript, XHTML, Java, .Net, PHP, C, C++, Python, JSP, Spring ... You can make it much tighter by using list comprehensions. The function below will perform all of the puzzle checks and return all possible moves for a particular row and column given a particular puzzle, although I used characters instead of ints (you can transform by switching that part to m+1 for m in range(9)). A Sudoku puzzle is an example of what’s called a constraint satisfaction problem (CSP). One way to tackle CSPs programmatically is to use the Microsoft Solver Foundation (MSF) library. Although it’s highly unlikely you’ll ever need to solve a Sudoku puzzle as part of your normal work responsibilities, there are at least three reasons why ...
