Textbooks
There is no single textbook for this course. Instead, I have drawn materials mostly from the following sources, available from the University of Liverpool library (either in print or electronically). The following two books cover much of the material covered in COMP526:
- CLRS: Introduction to Algorithms by Cormen, Leiserson, Rivest, and Stein.
- SW: Algorithms by Sedgewick and Wayne.
CLRS is the probably the “modern standard” reference text on algorithms. SW is less expansive, but focuses more on the text processing algorithms that we will study in this module. (Is is also the more accessible of these two books.) Additionally, I have used the sections of the following texts in preparing materials for this module:
- Gusfield: Algorithms on Strings, Trees, and Sequences by Gusfield.
- KT: Algorithm Design by Kleinberg and Tardos.
- MacKay: Information Theory, Inference, and Learning Algorithms by MacKay.
- SMDD: Sequential and Parallel Algorithms and Data Structures by Sanders, Mehlhorn, Dietzfelbinger, and Dementiev.
Occasionally, I will also link to other resources. See the weekly schedule below for relevant readings for each lecture.
