Artificial intelligence is an area that has constantly fascinated me, perhaps because it tries to approach what is the most mysterious in our universe: our capacity for elaborate reasoning which gives us our remarkable intelligence. Perhaps also then because, by studying intelligence through machines, we always discover a little more about ourselves.

Before we begin, I have to confess: I don’t like crosswords. I understand that they can be interesting brain challenges but, from my point of view, they require too much general knowledge or verbal skills (which I do not have) and not enough logic. However, I do like logical riddles and that’s probably why I would never have written this article without the help of Sudoku. All the source code related to this article is available on GitHub.
