…appears to be being re-posted because the book is now available on Amazon: https://www.amazon.com/dp/1792644833 The text used to only be available via a PDF. Highly recommend if you're learning about algorithms, might buy a copy myself just to support Jeff (and add my own notes into the book).
on “Algorithms book, by Jeff Erickson” ↗…programming challenges with online judging, etc). In addition to what others have mentioned, here are some example resources you might prefer for a beginner-intermediate level intro: 1. (free online) Algorithms by Dasgupta, Papadimitriou, and Vazirani http://algorithmics.lsi.upc.edu/docs/Dasgupta-Papadimitriou-... 2. (free online) Algorithms by Jeff Erickson https://jeffe.cs.illinois.edu/teaching/algorithms/…
on “Ask HN: Looking for a book on algorithms and data structures” ↗It depends? 1. Programming Philosophy? - The Unix Philosophy - 97 Things every programmer should know 2. CS Fundamentals - The Elements of Computing Systems by Simon - Algorithms by Jeff Erickson 3. Data Science - Programming Collective Intelligence by Toby Segaran - Deep Learning by Ian Goodfellow & Yoshua Bengio
on “Ask HN: Books about Programming Concepts?” ↗This is Jeff Erickson's free textbook (really a set of detailed lecture notes) on Algorithms, a course that Jeff teaches at UIUC and routinely wins teaching awards for. Definitely worth your time. Jeff is working on a similar set of notes for Computational Topology: http://www.cs.uiuc.edu/~jeffe/teaching/comptop/schedule.html.…
on “Algorithms Course Materials” ↗All good resources. I'd also add Algorithms, Etc. by Jeff Erickson. http://jeffe.cs.illinois.edu/teaching/algorithms/ And for practice, Google Code Jam past problems are quite challenging ;) https://code.google.com/codejam/
on “Ask HN: What's the best algorithms and data structures online course?” ↗Is this an ask for resources or an ask for people to join. If the former, I recommend jeff Erickson's freely available Algorithms textbook
on “Ask HN: Algorithms and Data Structure Resources” ↗Algorithms, Etc. by Jeff Erickson chapter on dynamic programming is great, especially that part: In a nutshell, dynamic programming is recursion without repetition. Dynamic programming algorithms store the solutions…
on “Ask HN: What books do you keep on your desk?” ↗I'm a big fan of Algorithms by Jeff Erickson (free to download at http://jeffe.cs.illinois.edu/teaching/algorithms/)
on “Ask HN: What are the most fundamental books on computer science?” ↗> there’s a reason these people are self publishing. ??? What in the paranoia is this, do you think the same of Jeff Erickson who self publishes his book on Algorithms? Or no, because he's a professor? I get that you need to use surface-level signals to determine if something is worth your time, but the opposite is not "this is crap" the opposite is "I don't know if…
