There should be references to problems for each topic at online judges. Like this one:

Learning algorithms per se is only a small part of training. Much bigger part of training is learning how to recognize these algorithms in problems.

After reading about some algorithm, I always solve a couple of related problems.

P.S. Looks well-written. Bookmarked. I appreciate the effort of the author to create this book.
