Solving Sudoku puzzles is one of the most popular pastimes in the world. Puzzles range in difficulty from easy to very challenging; the hardest puzzles tend to have the most empty cells. The current paper explains and compares three algorithms for solving Sudoku puzzles. Backtracking, simulated ...
Techniques with several squares at the same time When solving sudoku in previous algorithms we worked only with one square for which we determined a possible number. Or more precisely, we worked with a single number for which we wanted to find a suitable square. However, it is not possible ...
Sudoku is one of the most popular puzzle games of all time. Today, Sudoku is based on simple rules of placing the numbers from 1 to 9 in the empty cells of the Sudoku board. After solving the Sudoku, each row, column, and mini grid should have only one o
The following link contains useful information about methods for solving sudoku puzzles. You can use any of them, but in my experience item 3 (pencilling in) works well with a computer model of the puzzle. Your program will, however, have to use some other techniques (probably pairs and tri...
solving it without taking any notes. Yes, with the right combination of techniques you can solve even the most difficult puzzle without taking any notes. If you follow along, I will break these techniques down for you in future posts. May all your puzzles be challenging and worth of your ...

Solving a Sudoku puzzle is really a special kind of search, and as such I can take advantage of standard search algorithms. A common search algorithm is depth-first search (DFS), which is typically taught as one of the first algorithms in a data structures and algorithms class in college....
Let’s zoom out a bit. Sudoku is an example of a constraint problem. Most “solving sudoku” tutorials use eitherbacktrackingorconstraint propagation. These same techniques apply to all constraint problems, and since such problems are so widespread, it doesn’t make sense to custom build an al...
As such, for those being acquainted with computers, it becomes an irresistible challenge to build a computing engine for Sudoku solving. Many Sudoku solvers have been developed recently, using advanced techniques and algorithms to speed-up the computation. In this paper, we describe a hardware ...
