sudoku-resolver

This is just a program for fun. I know it’s not optimized.

This project is in re-build - check sudoku-solver/main

How to use

To use this program you need to create a text file with the sudoku (with 0 when there aren’t number) named sudoku1.txt like this :

5 0 0 0 0 0 0 9 4
0 0 9 0 0 0 0 5 0
0 4 0 0 0 0 2 0 0
0 2 0 5 0 0 8 0 0
0 0 4 0 0 1 0 7 0
8 0 0 0 3 0 0 0 6
0 0 2 0 0 7 0 1 0
0 3 0 9 0 0 0 0 0
6 0 0 0 4 0 0 0 8

This text file sudoku1.txt needs to be next to the program code.c Then compile and execute code.c and the program will solve the sudoku on the screnn and in a file

Documentation

This program use two method to solve the sudoku.

-The 1rst method is the logical one, sudoku have proprety to be solve.

But in a certain case, the sudoku can’t be solve because you need to add a number.

• In this case, the 2nd method is used : it “bruteforce” the sudoku (in reality it just bruteforce at maximum 2 numbers, but we can change this number of course).

Possible issues

• Maybe you don’t create correctly the sudoku1.txt file
• Maybe you are trying to solve a sudoku with the brutforce method, and it’is need more numbers to brutforce.

You can change a value to activate the log !
