brute force != solving a sudoku

You can't brute force a sudoku, it would take about 1450 billion years using a super duper computer using only brute force. But you could use different solving techniques. Quote Peter Norvig:

"First, we could try a brute force approach. Suppose we have a very efficient program that takes only one instruction to evaluate a position, and that we have access to the next-generation computing technology, let's say a 10GHz processor with 1024 cores, and let's say we could afford a million of them, and while we're shopping, let's say we also pick up a time machine and go back 13 billion years to the origin of the universe and start our program running. We can then compute that we'd be almost 1% done with this one puzzle by now." http://norvig.com/sudoku.html

I actually sort my books by topic, by title, by author and by year simultaneously. All my books is symlinked from a folder where I have all my books.
(Well I would do that, if I had some more books, but I only have a few scattered around my harddrives...)
My music is only sorted by artist/album....
