Backtracking - Wikipedia

★ ★ ★ ★ ★

Backtracking can be thought of as a selective tree/graph traversal method. The tree is a way of representing some initial starting position (the parent node) and a final goal state (one of the leaves). Backtracking allows us to deal with situations in which a raw brute-force approach would explode into an impossible number of choices to consider.

11/24/2017 · Recursive backtracking is a well-known brute-force search algorithm. As long as a Sudoku puzzle is valid, recursive backtracking can solve it by trying all possible numbers systematically. When the puzzle has many solutions, it will output the lexicographically first one. If it has no solution, the output is the original unsolved puzzle.

Some hobbyists have developed computer programs that will solve Sudoku puzzles using a backtracking algorithm, which is a type of brute force search. Backtracking is a depth-first search (in contrast to a breadth-first search), because it will completely explore one branch to a possible solution before moving to another branch. Although it has been established that approximately 5.96 x 11 26 ...
