He makes some interesting remarks later in the introductory notes. Among them are an emphasis on practice of algorithm design and analysis, and a curious claim that "we" (the course staff) cannot teach the students how to do well in the class, but can provide the tools that will (hopefully) enable the students to do well. This is reasonable, I suppose (if not reassuring). My only criticism of the class is that he's part of the camp that doesn't provide solutions to problems, claiming that more is gained from attempts to solve the problems than looking at the answers. (If you recall, my response to such arguments is that solutions are helpful when they explain how the solutions are arrived at, what common techniques may be employed in the solutions, and possible pitfalls one might encounter in attempting solutions).
At any rate, it's good to see professors using familiar examples to illustrate key concepts. This helps develop intuition and problem-solving skills.
