Hi, I'm the author.<p>For those who haven't heard about the book yet: it is a practical description of the main data structures and algorithms in use today. The book is also featuring a presentation of the most important algorithm development techniques, as well a examples of the real-world use cases in each chapter. It uses Common Lisp as an implementation language, and also contains a crash course into the language if you are not yet familiar with it.<p>For those who have already seen or even read the previous version published on Leanpub, here is a summary of the updates: <a href="http://lisp-univ-etc.blogspot.com/2021/02/programming-algorithms-in-lisp-is-out.html" rel="nofollow">http://lisp-univ-etc.blogspot.com/2021/02/programming-algori...</a><p>As usual, AMA.
