Solving methods

Solver Sudoku is a deep search (as opposed to a wide search) because it completely checks the branch for a possible solution before moving to another branch. Although it has been established that there are approximately 5.96 x 1126 final grids, the brute force algorithm can be a useful way to solve Sudoku puzzles.

Sudoku solving algorithm

Sudoku solving algorithm visits blank cells in a certain order, enters numbers one at a time, or returns if the number is incorrect. In short, the Sudoku solver would solve the puzzle by putting the number “1” in the first cell and seeing if it could be there. If there are no violations (checking for row, column, and field constraints), the Sudoku-solving algorithm moves to the next cell and puts “1” in it.

Stochastic search or optimization methods
