I read this because it’s the textbook for the OMSCS algorithms class. The book is relatively short and does a pretty good job with the material it covers. Probably the most memorable thing that was new to me was the so-called “master theorem” for determining the runtime of recursive algorithms.
I have no idea what the quantum computing chapter was talking about, but that’s probably more a reflection of me not being ready to dive into that topic right now than of any deficiency in the book.
