I would have to say I am less excited about the topics promised in Volume 4 (supposedly Combinatorial Algorithms, but way too much time in the Facicles is spent on explicit enumeration) than those found in Volumes 1 (Fundamental Algorithms), Volume 2 (Seminumerical Algorithms) and Volume 3 (Search and and Sorting). I grew up with "The Art of Computer Programming," but I think not all of the volumes are equal or have aged similarly. For example Volume 2 now can be seen to fail to anticipate a lot of exciting results in pseudo-randomness, quasi-randomness and de-randomization. On the other hand Volume 3 is, due to our current obsession with search, possibly even more exciting than the day it was new.
