Last Friday I had a very interesting discussion with one of my fellow classmates about the possibility of a brute-force sudoku solver. Assuming that a puzzle might have about 10 preset spaces, we determined that it would take about couple thousand years to search through every single iteration, using modern computers available to consumers. My friend claimed that a brute force solver would not be practical, but having seen others create such things, I attempted to create my own.
