van Leeuwen Comment on Models of Computation

A magnificent piece of work! Models of Computation gives a
superb treatment of modern complexity theory, in a perfect textbook
style. Your book fills the gap which all of us felt existed too
long. Congratulations on this excellent contribution to our field.
