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.

Ratings and Reviews
Very challenging, but it just shows that you should never give up and keep believing in yourself! Thanks Prof. Tim for this excellent course. I do feel smarter than when I started, and had fun too (most of the time)!
This is the most challenging course of all the courses in the specialization
I really love this course. What the professor said was just to the points he wanted to convey and no not-related sentences. He controlled extremely well about to what level of details to unfold. Last but not least, he adds complexity of problems gradually. I saw he taught a follow-up course at Stanford and I can watch the videos on Youtube. If the course were on Coursera, I would take it.

A great course with great assignments. Assignments really test your implementation skills as well as research skills. One should really use forums to ask doubts and give answers to solve these assignments.
