Introduction to Algorithms

This book provides a comprehensive introduction to the modern study of computer algorithms. It presents many algorithms and covers them in considerable depth, yet makes their design and analysis accessible to all levels of readers. We have tried to keep explanations elementary without sacrificing depth of coverage or mathematical rigor. Each chapter presents an algorithm, a design technique, an application area, or a related topic. Algorithms are described in English and in a "pseudocode" designed to be readable by anyone who has done a little programming. The book contains over 260 figrues illustrating how the algorithms work. Since we emphasize efficiency as a design criterion, we include careful analyses of the running times of all our algorithms. The text is intended primarily for use in undergraduate or graduate courses in algorithms or data structures. Because it discusses engineering issues in algorithm design, as well as mathematical aspects, it is equally well suited for self-study by technical professionals.

CLRS is a wonderful book and I learned a ton from it. https://en.wikipedia.org/wiki/Introduction_to_Algorithms , https://www.cs.mcgill.ca/~akroit/math/compsci/Cormen%20Intro...

I am a software developer and most of my work is in AWS. I don't have a CS degree, but have taken a handful of lower level courses. I haven't studied PLT much at all, but I really like the lambda calculus.

As for books, I don't have many to recommend beyond Michaelson's book except maybe a few classics like Cormen's Introduction to Algorithms, Structure and Interpretation of Computer Programs, and Types and Programming Languages.

What have you made that was cool? And what are some books you recommend?

That's a sad indictment of tech.

Most underlying technology is timeless (see TAOCP, SICP, CLRS, K&R, GoF, Dragon Book, Beej's Guide, Sipser,...); but we seem set on producing an endless, pointless, churn of frameworks and minor language differences in the name of progress.

True enuf, but how often do you actually refer to the books underlying ideas? I've had (now gone, presumably) TAOCP on my bookshelves for years, but how often did I use it? Stuff on RNG a bit, I guess...

Sedgewick's Algorithms book is great for practical learning but too tied to Java and implementation details. It is a bit shallow on theory, though the community and resources for other languages help.

That said, I personally prefer Introduction to Algorithms (CLRS) for its formal rigor and clear proofs, and Grokking Algorithms for building intuition.

The broader goal of this project is to build a well tested, reference quality set of implementations in C, Python, and Go. That is the next milestone.

Those algorithms implement so random to me, with lack of explanation, no test cases, no formal proof, and often inconsistent naming or structure across languages. Many repositories like TheAlgorithms are great collections, but they feel more like code dumps than true learning resources. You can find an implementation of Dijkstra or QuickSort, but often there is no context: why it works, how to prove it correct, what the complexity is, or how to test it against edge cases. For someone who wants to learn algorithms deeply, that missing layer of reasoning and validation is critical.

No organization for learners either. It jumps straight into implementations without a logical flow from fundamentals. I want to build something more structured: start from the very foundation (like data structures, recursion, and complexity analysis), then move to classical algorithms (search, sort, graph, dynamic programming), and eventually extend to database internals, optimization, and even machine learning or AI algorithms. Basically, a single consistent roadmap from beginner to researcher level, where every algorithm connects to the next and builds intuition step by step.

Another very good resource for beginners is https://www.hello-algo.com. At first, i actually wanted to contribute there, since it explains algorithms visually and in simple language. But it mostly covers the basics and stops before more advanced or applied topics. I want to go deeper and treat algorithms as both code and theory, with mathematical rigor and formal proofs where possible. That is something I really liked about Introduction to Algorithms (CLRS) and of course The Art of Computer Programming (TAOCP) by Knuth. They combine reasoning, math, and practice. My goal is to make something in that spirit, but more practical and modern, bridging the gap between academic books and messy open source repos.
