A beautiful algorithm discussion ends this book. As I have probably mentioned before, I really enjoy reading about alternative solutions to problems combined with discussions about the pros/cons. In this case, the problem is simple to ask yet has rich answers that depend not only on abstract math but practical numerical computation considerations.
There is an interesting website where you can tee-up problems, in some cases with a bounty, to a world-wide audience. This type of site might have been a help to the author.
