A WIP sudoku solving library
Improve performance, potentially via using SIMD, and or GPU
Add sudoku difficulty grading, potentially by counting the number of iterations needed to solve
Add sudoku generation from a seed sudoku
To get the first solution to each sudoku in input: msolve solve < sudokufile.txt > output.txt
To get the solution for each uniquely solvable sudoku in input: msolve -u < sudokufile.txt > output.txt
To get the first N solutions to each sudoku in input: msolve solve -c N < sudokufile.txt > output.txt
To get information about the sudoku file: msolve info < sudokufile.txt
Example output for info: 0 Solutions: 486451, 1 Solution: 763, 2+ Solutions: 12786
To list all puzzles with a single unique solution: msolve select -v < sudokufile.txt > output.txt
To list all puzzles with at least one unique solution: msolve select < sudokufile.txt > output.txt
To get the number of solutions of each puzzles, up to a maximum of N: msolve count_solutions N < sudokufile.txt > output.txt
