The Art of Computer Programming, Volume 4A: Combinatorial Algorithms, Part 1
By Donald E. Knuth
The book is "Volume 4A," because Volume 4 has itself become a multivolume undertaking. This book alone includes approximately 1500 exercises, with answers for self-study, plus hundreds of useful facts that cannot be found in any other publication. Knuth’s multivolume analysis of algorithms is widely recognized as the definitive description of classical computer science. The first three volumes of this work have long comprised a unique and invaluable resource in programming theory and practice.
