    Thank you for teaching me this course. I learned a lot of new things, including Divide-and-Conquer, MergeSort, QuickSort, and Randomization Algorithms, along with proof for their asymptotic runtime

    I thought this was an excellent overview of the basics of sorting and recursion algorithms and taught at a rigorous level appropriate for college students.

    I loved it. It's challenging. Definitely requires some thought outside of what he videos cover for some of the quiz questions, but still totally doable.

    Very good review of divide and conquer algorithms, however, I only recommend for those who are willing to put in the hard work as I found it challenging.

    Very good course. Teaches the basics of algorithms very well. Lectures are great but I mostly studied from textbook (you can find it on amazon for $10).

    Really enjoyed watching the lectures and Prof Roughgarden's explanations. He did a good job diving just deep enough into the math without losing me.

    Remember that the course is based and more focused on the analysis part rather than the actual implementation of the algorithm part. Tim is genius

    Hi,

    Great professor, deep dives into key theorems, which bolsters confidence in the subject. Even complex theorem is taught in a friendly manner.

    Tim Roughgarden does an amazing job at explaining this topic. The only very very small downside is, that video and voice are not always in sync.

    An excellent course. Frees your mind from the high school paradigm of procedural approach to Maths at the expense of pure, ground up reasoning.
