Online courses on algorithms or a small but capacious book?

Question

Algorithms

Hello.
You need a small online course (free) or a small but capacious book on algorithms.
Can you advise what?
Sometimes I stumble upon "there is a Stanford free course in algorithms", but I just can't find it, despite the huge output in Google.

Answer 1

It is on algorithms (and not on their analysis and design) that there is a wonderful free course with practical tasks on the courser. Here is the first part . I note that the tasks are checked according to such parameters as style, correctness and efficiency. 6 weeks each piece. There is a book for the course.

Answer 3

I am also studying algorithms now: according to two books: "Algorithms" by Rod Stevens and "Algorithms for Beginners" by Panos Louridas. I won't recommend the latter, but Rod Stevens is good. And I’m also taking a course at https://shultais.education/courses/algo - there are video lessons and you can solve problems right away, although there are not so many tasks.
