Some hobbyists have developed computer programs that will solve Sudoku puzzles using a backtracking algorithm, which is a type of brute force search. [3] 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.
'digit-single'; originally called Number Place) [1] is a logic-based, [2] [3] combinatorial [4] number-placement puzzle. In classic Sudoku, the objective is to fill a 9 × 9 grid with digits so that each column, each row, and each of the nine 3 × 3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contains all of the ...

By your thinking we have 4*4*4*4 = 256 combinations in a 2x2 box, while in a Sudoku grid we have 4! = 24 combinations, giving 1/10 from each box and thus there are 1/10000 Sudoku grids among 4x4 Latin squares... — chaotic_iak 12:10, 10 January 2014 (UTC) This isn't a blog or forum about the article subject.
