Think Complexity

What Hacker News says

   Allen Downey (author of the above) has a number of books on computer science-y things. You can buy hardcopies but I think all of them are also just freely available.

   Here's a few:

   Think Complexity

   https://github.com/AllenDowney/ThinkComplexity2

   Think DSP

   https://github.com/AllenDowney/ThinkDSP

   Think Stats

   https://github.com/AllenDowney/ThinkStats/

   Think Bayes

   https://github.com/AllenDowney/ThinkBayes2/

   Also:

   - Think Python

   - Think Data Structures

   - Think Java

   - Think Perl6 (!)

   - Modeling and Simulation in Python

   - Probably Overthinking It

   And more [1]. He's a prolific writer, and very generous for offering many of them for free. I read several of them online or through O'Reilly, and bought printed copies just to appreciate his work. Really enjoyed Think DSP, Think Complexity, Think Bayes, etc.

   This is a good list of books. Unfortunately many of the links are broken? Probably just my luck, but the first few "with Sage" books I excitedly selected unfortunately 404'd. I'll send an email.

   > Moreover, the American Institute of Mathematics maintains a list of approved open-source textbooks. https://aimath.org/textbooks/approved-textbooks/

   I also like the (free) Green Tea Press books: Think Stats, Think Bayes, Think DSP, Think Complexity, Modeling and Simulation in Python, Think Python 2e: How To Think Like a Computer Scientist https://greenteapress.com/wp/

   And IDK how many times I've recommended the book for the OCW "Mathematics for Computer Science" course: https://ocw.mit.edu/courses/electrical-engineering-and-compu...

   There may be a newer edition than the 2017 version of the book: https://courses.csail.mit.edu/6.042/spring17/mcs.pdf

   Think Python, Think Complexity, and Think Statistics are all really excellent. Downey is an artist of CS pedagogy.

   You mentioned getting to grips with complexity analysis. Has she looked at the book Think Complexity[1]? It seems pretty cool and related to that area of study.
