This article is "OK". I wish it was ordered differently. My complaint is it spends wayyy too much time on heuristics (2nd page) before it discusses the implementation (3rd page). I think it's important to get an overall idea of what the algorithm is before you focus on the minute details of a part of it. Plus, when it discusses the implementation, it doesn't spend enough time explaining it.
