> During a Yahoo Hack Day last year, I wrote a distributed pentomino solver
> that used map/reduce and Knuth's dancing link algorithm to solve pentomino
> tile placement problems. As a side benefit, I also wrote a sudoku solver
> using the dancing link library, but the sudoku solver is so fast that there
> is no need to distribute it. Anyways, I think it makes an interesting example
> of how to do some interesting cpu-heavy distribution in Hadoop.
