This is beautifully presented. Addressing the author(s): I don’t know much about the topic area but you made it interesting, and it is a trove of cool tricks and techniques (sure, bit manipulation is basic but it’s fun to see how you put it all together to solve the problems). And how you analyze the performance. Look forward to coming back to this after I get more up to speed on linear algebra.
