In my previous post I wrote about a Sudoku solver in SQLServer and I thought it wouldn’t take long to have Sudoku solver in PL/SQL. Actually, when I told this to Steven Feuerstein, he told me he got an email from someone who has already done this. He put his solution on his website with explanation and a download possibility. The explanation is very good and it seems to be a really simple algorithm, but you must think of it ;-). Like most solutions to problems are actually really simple if you think of the solution. It’s the coming up with the solution that is often times the hardest.
