This tutorial will show you how to create a sudoku solver using python and the backtracking algorithm. We will compare this against what is known as the naïve algorithm and see its massive advantages.
Aug 15, 2020 · The first step is to generate possible candidates for each empty cell by scanning rows, columns and sub-grids. Whenever there's only one possible candidate, the cell is filled with that value. Next, the solver guesses one value and the process continues recursively until a valid solution is found.
