About this course: The primary topics in this part of the specialization are: shortest paths (Bellman-Ford, Floyd-Warshall, Johnson), NP-completeness and what it means for the algorithm designer, and strategies for coping with computationally intractable problems (analysis of heuristics, local search).
Who is this class for: Learners with at least a little bit of programming experience who want to learn the essentials of algorithms. In a University computer science curriculum, this course is typically taken in the third year.

Need more explanatory answer sets.
Thanks for the instructor.
The lectures gives much more information than previous 3-courses. And I often found I need extra practices (on-line alg interview problems) and reading (CLRS, e.g.) to grasp the course materials. The programming assignments are also more demanding. However, after finishing this course, I believe I have achieved better and deeper understanding of Algorithm design and analysis than I could imaged before taking this final NP course. And I am looking forward to learn more from Professor Tim Roughguarden's 'a second course on Algorithm' on youtube. Thank you very much, professor! Your knowledge and passion is totally incredible! And Thank you very much for fellow students on the discussion forums. It has been a great pleasure to learn with you all :)
