The course is great, it both challenging and interesting. The only one thing that I was lacking is visualisation. A lot of information/parts of algorithms explanations/theorem proofs is passed verbally and considering not triviality of that information it's hard to perceive and understand that without proper visualisation (algorithms animation/schemes/diagrams etc.).

Totally the course and specialization are awesome. In this course, the explanation sometimes wasn't enough for such complex problems. At least I understood where I hare a rather big lack of knowledge and need to get the new courses.

Great one for people with advanced understanding! Others will find it slightly hard to follow!

Well the course only got harder but still stellar explanation.

Course is short for the topic complexity

diffcult

so hard

Sometimes is really hard to understand, I wish more examples and visualization rather than straightforward speech.

Can be expanded more. Some of the quizzes are too hard.
