Ebook: Algorithms: Design Techniques and Analysis

I have been using this book as a second reference in my Algorithm Engineering class during the whole semester. I found it extremely useful for its nice structure, content and diversity of subjects treated, especially the ones in computational geometry such as Geometric Sweeping and Voronoi diagrams, for instance. I believe this book should be useful to any student taking algorithms class for its structureness, clearness, and completeness.
