“This text takes (grouping algorithms by design) to a whole new level."
-UNLV
"The manner in which algorithms are described with respect to both their structure (English language description, pseudo-code) and behavior (English language descriptions, execution trees) is excellent."
-University of Michigan
"The exercises provide a good mix of algorithm tracing, algorithm design, mathematical proof, and program implementation"
-University of Alabama
