What do you recommend for algorithms?

Question

Algorithms

Hello! Maybe someone will throw some good advice on what to read on algorithms. So far I've read:

• Grokkaem Algorithms - A. Bhargava. I liked that he explains everything in simple language, but probably from here, as a consequence, there are a lot of errors. I would like a little more serious and deeper book.
  
• Algorithms. Introductory course. Thomas Kormen. I liked everything, but too little, it was the introductory course that turned out.
  
• Algorithms. Construction and analysis. Thomas Kormen, Charles Leyzerson, etc. I just got acquainted with this book and already liked the number of interesting algorithms that are described in it, but I don’t like the pseudocode at all (I liked it much more in the introductory course).
  

I heard a lot about Knuth, but it scares me that there is a lot of mathematics, which, as I understand it, you need to know very well.

Answer 1

Nothing.
Start from the task and read on Wikipedia.
