Dancing links Visualizer Have you ever wondered what could be the fastest method to solve a Sudoku? There is a name for it. The release 2. , 2014). 0 handles 9 * 9 and 16 * 16 sukoku grids and checks if the grids are valid or not. Imagine the simplest most brute-force method of trying to solve a Sudoku puzzle. . Knuth Sudoku solving Sudoku solving is an NP-complete problem, therefore, finding a way to solve an 'n by n' Sudoku board in polynomial time is very unlikely (Kumar et al. This is an implementation of Donald Knuth's Algorithm X ("dancing links"). Oct 30, 2022 · Rapidly Solving Sudoku, N-Queens, Pentomino Placement, and More, With Knuth’s Algorithm X and Dancing Links. It can easily be adapted to function as a backtracking algorithm to solve sudokus. Sudoku is one such special case of the Exact Cover problem. DLXSolver 2. com is a free online automatic sudoku solver that solves almost any sudoku puzzle in matter of second. This program was developed in 2010, based on the Sudoku solver ZeroDlx written by Jim Schirle and implementing the Dancing Links algorithm of D. Oct 24, 2025 · And that’s it - we’ve built a complete Sudoku Solver using Algorithm X and Dancing Links! Starting from the rules of Sudoku, we reduced it to an Exact Cover problem, implemented Knuth’s elegant algorithm, and watched the puzzle solve itself. Sep 26, 2014 · Part 2, where we introduce the Dancing Links algorithm for solving Sudoku might be slightly more challenging. How to solve Dancing Links Sudoku? Solving a "Dancing Links" puzzle requires the use of a special solving technique known as "dancing links. Algorithm X is a recursive, nondeterministic, depth-first, backtracking algorithm that finds all solutions to the exact cover problem. The Dancing Links algorithm was created by Donald Knuth, and was not originally created to solve Sudoku puzzles. It applies Javascript, Brute Force method and Dancing Links Algorithm for quick solution. The Dancing Links algorithm devised by Don Knuth has so far outrun every other method that has competed against it. Dr. Dancing Links (Algorithm X) Knuth's exact cover algorithm: Models Sudoku as an exact cover problem Uses circular doubly-linked lists for efficiency Very fast and reliable Industry-standard approach Complexity: Efficient for most practical Sudoku puzzles Funcionalidades para generar y resolver, crear y verificar tableros de Sudoku utilizando el algoritmo Dancing Links (DLX). 0 was rewritten in 2025 to explore the solving process of the Dancing Links. 4. There are various techniques that researchers have developed to solve this problem . Furthermore, the progress of the solving process is Aug 31, 2023 · Introduction: Picture this: a secret dance of algorithms, choreographed to solve intricate problems with finesse and elegance. Donald Knuth’s Dancing Links Algorithm solves an Exact Cover situation. The Exact Cover problem can be extended to a variety of applications that need to fill constraints. This is primarily a sudoku generator and solver, though it can be used to solve other exact cover problems. " This technique involves manipulating the links between the nodes in the grid in order to eliminate possibilities and determine which numbers can be placed in each cell. About Python implementation of Knuth's Dancing Links (dlx) algorithm to solve set cover. Take the first empty square, and try putting all the numbers from \ (1\) to \ (9\) into it one by one. Maybe you'll find it helpful. Oct 5, 2009 · I created this Sudoku Solver Visualizer that implements Dancing Links and several other algorithms including Greedy Best First Search and Backtracking. It is elegant, simple, but very elusive. Some of the better-known exact cover problems include tiling, the n queens problem, and Sudoku.
